The volume of the cup whose height is 8.3 cm and radius is 2.37 cm in cubic centimeters, by rounding off nearest tenth is 146.4 [tex]cm^{3}[/tex].

Volume of cup by rounding off nearest tenth = 146.4 [tex]cm^{3}[/tex].

The volume V of a cylinder with radius r is the area of the base B times the height h .

V=Bh  or  V=π[tex]r^{2}[/tex]h

It is given that,

height= 8.3 cm

Circumference = 14.9 cm

By using the circumference we first find the radius of circular base or top,

Circumference of the circle = 2πr

14.9= 2 x  3.14 x r

14.9= 6.28 x r

r= [tex]\frac{14.9}{6.28}[/tex]

r= 2.37 cm

Hence, the radius of the circle is 2.37 cm.

Volume of cup( cylindrical shape ) = π[tex]r^{2}[/tex]h

                                                         = 3.14 x 2.37 x 2.37 x 8.3

                                                         = 26.062 x 5.616

                                                         = 146.364 [tex]cm^{3}[/tex]

                                                         = 146.4 [tex]cm^{3}[/tex] (nearest tenth)

The volume of the cup in cubic centimeters, by rounding off nearest tenth is 146.4 [tex]cm^{3}[/tex].

Answer:

47

Step-by-step explanation:

Determine if the sequence is arithmetic or geometric.

The difference between each term in the sequence is constant, so this is an arithmetic sequence.

To calculate the common difference, subtract one term from the next term:

14.5 - 8 = 6.5

21 - 14.5 = 6.5

27. 5 - 21 = 6.5

34 - 27.5 = 6.5

40.5 - 34 = 6.5

So the common difference is 6.5

To find the next term in the sequence, add 6.5 to the last term given:

40.5 + 6.5 = 47

The value of the coefficient b in the linear equation 5x +by =17 is -4

The pair of values are given as:

(x,y) = (-3,-8)

The equation is given as:

5x +by =17

Substitute values for x and y in the equation

-5 * 3 - 8 * b =17

Evaluate the product

-15 - 8b =17

Add 15 to both sides

-8b = 32

Divide both sides by -8

b = -4

Hence, the value of the coefficient b is -4

Answer:

n*8 = n+13

Step-by-step explanation:

To find the equation, we must first disect the sentence.  A product of a number and 8. This means a number times 8. A number n times 8. n*8.  Next, is equal to. This means add an equal to sign after n*8.  n*8 = . The sum of the number (n) and 13. This means n+13.  So, put it all together:

n*8 = n+13

The two angles shown are vertical angles which men they equal each other:

9n = 8n + 8

Subtract 8n from both sides:

N = 8

->Solution

i) 9n = 8n+8 [ V.O.A. vertically opposite angles ]

or, 9n - 8n = 8

or, n = 8

therefore, value of n is 8

Now,

ii) 9n = 9 X n = 9 X 8 = 72 degrees

iii) 8n + 8 = 8 X 8 + 8 = 64 + 8 = 72 degrees

area of triangular prism:

Answer:

Step-by-step explanation:

A = 10 cm

B = 8 cm    {base of the triangle}

C =  2 cm

D = 6 cm   {height of the triangle}

Area of the triangular prism = (A + B + D)*C + base * height

                                               = (10 + 8 + 6)*2 + 8*6

                                               = 24*2 + 48
