Two chords PQ and ST of length 6cm and 10cm respectively of a circle are parallel to each other and are on opposite side of its center. If the distance between PQ and ST is 5cm. Find the radius of the circle

Answers

Answer 1

Answer:

Draw two parallel chords AB and CD of lengths 5 cm and 11 cm. Let the center of the circle be O. Join one end of each chord to the center.

Draw two perpendiculars OM and ON to AB and CD, respectively, which bisects the chords.

Two chords AB and CD of lengths 5 cm and 11 cm respectively of a circle are parallel to each other and are on opposite sides of its center. If the distance between AB and CD is 6 cm, find the radius of the circle.

Thus, MB = 2.5 cm and ND = 5.5 cm [The perpendicular drawn from the center of the circle to the chords bisects it.]

Let OM = x and ON = 6 - x

Consider ΔOMB

By Pythagoras theorem,

OM2 + MB2 = OB2

x2 + 2.52 = OB2

x2 + 6.25 = OB2..................(1)

Consider ΔOND

By Pythagoras theorem,

ON2 + ND2 = OD2

(6 - x)² + 5.52 = OD2

36 + x2 - 12x + 30.25 = OD2

x2 - 12x + 66.25 = OD2............... (2)

OB and OD are the radii of the circle. Therefore OB = OD.

Thus, OB2 = OD2

Equating (1) and (2) we get,

x2 + 6.25 = x2 - 12x + 66.25

12x = 60

x = 5

Substituting the value of x in (1),

OB2 = x2 + 6.25

OB2 = 52 + 6.25

OB2 = 31.25

OB = 5.59 (approx.)

Thus, we get the radius of the circle = 5.59 cm.

Answers

The equation of the graph G(x) is (x - 4)^2 + 1.

We have given the graph below have the same shape.

We have to find the equation of the graph g(x).

We have to find the equation of g(x) by using the phase shifting.

What is the shifting of the graph?

A shift is a rigid translation in that it does not change the shape or size of the graph of the function.

Here we can see that the vertex of the graph in f(x) is (0,0) and the

vertex of the graph is g(x) is (4,1)

Therefore [tex]x^2[/tex] is replaced by [tex](x-4)^2[/tex].

and  is shifted upward one unit therefore we get

[tex]G(x)=(x-4)^2+1[/tex]

Therefore we get the graph of g(x)= (x - 4)^2 + 1.

Since the diameter is the radius multiplied by 2, the radius of the circle is 8.

The volume of a sphere is the amount of space in it

The volumes of the spheres are 24416.64, 113.04 and 310181.76

How to determine the volume of the spheres?

The volume of a sphere is calculated using:

V = 4/3 πr^3

When the radius, r = 18, we have:

V = 4/3  * 3.14 * 18^3

V = 24416.64

When the radius, r = 3, we have:

V = 4/3  * 3.14 * 3^3

V = 113.04

When the radius, r = 42, we have:

V = 4/3  * 3.14 * 42^3

V = 310181.76

Hence, the volumes of the spheres are 24416.64, 113.04 and 310181.76

Derek need to buy 4 sheets of plywood for $9 each and some boxes of nails. He has $60 to spend. If each box of nails costs $5 at most how many boxes can he buy?

Answers

Answer:

4

Step-by-step explanation:

4 sheets of plywood X 9$=36$

60$-36$=24$

24$ is left over to buy boxes of nails at 5$ each

24/5=4.8

Derek can buy 4 boxes of nails.

4 (plywood sheets) x 9 (price of sheets)= 36$
36$ (price of four plywood sheets) - 60$ (total sum) = 24$
24$ : 5$ (price per box) = 4.8, but he can’t but a fraction of a box so he can only buy 4 boxes of nails

A man earns Rs.9600 and he saves Rs.2400 in a month.What percentage does he spends?

Answers

Given Information :-

A man earns rs. 9600He saves Rs. 2400

To Find :-

The percentage of amount he spends

Solution :-

To find the percentage of expenditure, we must know how much amount does he really spend, thus :

➥ Expenditure = Earnings - Savings

➥ Expenditure = Rs. 9600 - Rs. 2400

➥ Expenditure = Rs. 7200

Now, we can find the percentage,

[tex] \sf \hookrightarrow Percentage_{expenditure} = \dfrac{Expenditure}{Earnings} \times 100 \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = \frac{7200}{9600} \times 100 \qquad \: \: \: \: \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = \frac{72 \cancel{00}}{96 \cancel{00}} \times 100 \qquad \quad \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = \frac{ \cancel{72}}{ \cancel{96}} \times 100 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = \cancel \frac{3}{4} \times 100 \qquad \qquad \: \: \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = 0.75 \times 100 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \sf \hookrightarrow Percentage_{expenditure} = \underline{ \boxed{ \orange {\frak{75\%}}}} \: \star \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ [/tex]

Applying the appropriate circle theorems involving angles formed by chords and tangents, we have:

1. x = 75°; y = 85°, z = 210°

2. x = 38°

3. x = 143°

What is the Angles of Intersecting Tangents Theorem?

The angle formed outside a circle when two tangents intersect equals half of the positive difference of the intercepted arcs, based on the angles of intersecting tangents theorem.

What is the Angles of the Intersecting Chords Theorem?

The angles of intersecting chords theorem states that, half the sum of the intercepted arcs equals the vertical angle formed by two chords in a circle.

What is the Inscribed Angle Theorem?

According to the inscribed angle theorem, the measure of an inscribed angle in a circle = 1/2(measure of intercepted arc)

1. x = 180 - 105 (opposite angles in a cyclic quadrilateral are supplementary)

x = 75°

y = 180 - 95 = 85°

z = measure of intercepted arc HEF = 2(105) [inscribed angle theorem]

m(HEF) = 210°

2. x = 1/2(218 - 142) [angles of intersecting tangents theorem]

x = 1/2(76)

x = 38°

3. x = 1/2(146 + 140) [angles of intersecting chords theorem]

x = 1/2(286)

x = 143°
