What is the length of the arc subtended by the angle measuring 4 radians?
A.
4 cm
B.
2 cm
C
16 cm
D
8 cm
Answers
Answer:
D. 8 cm
Step-by-step explanation:
Given :
Let the length of the arc be = l
radius of the arc, r = 2 cm
degree of angle subtended at the center by the arc, θ = 4 radian
Now we know that the angle subtended by an arc at the center of the circle whose radius is 2 cm will be,
θ = l/r
Therefore, we can write,
l = θ x r
l = 4 x 2
= 8 cm
So the length of the arc is 8 cm.

Answers
Answer:
B
Step-by-step explanation:
Assuming the denominator is 16 (to fit with the second part), 9+3 is 12 and 12/16 is 3/4.
If we take 7 from 16 we also get 9, which is thus 1.

A remote ranch has a cylindrical water storage tank. It has a vertical central axis, a diameter of 16 ft, the sides are 5 ft high, and it is full to the brim. The depth of this water is 4 ft. How much work (in ft-lb) would be required to pump all of the water over the upper rim? (Use the fact that water weighs 62.5 lb/ft3. Round your answer to the nearest integer.)
Answers
Answer and Step-by-step explanation:
Given: diameter = 16ft height = 5 ft. Depth = 4ft
Work =?
As we know that work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
= 62.5 ʃ04 (5-y) ∏ (4y) dy
=62.5∏ ʃ04 (5-y) 4ydy
=62.5∏ ʃ04 20y-4y2dy
=62.5∏ |20y2/2 – 4y3/3|04
=62.5∏ |74.66|
=14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is :
Given: Diameter = 16ft Height = 5 ft. Depth = 4ftWork =?
Formula:work = force x distance
W= distance x density x volume
W= ʃ04 (5-y) 62.5x ∏ (d/2)2dy (area = ∏r2 , r= d/2)
W = 62.5 ʃ04 (5-y) ∏ (4y) dy
W =62.5∏ ʃ04 (5-y) 4ydy
W =62.5∏ ʃ04 20y-4y2dy
W =62.5∏ |20y2/2 – 4y3/3|04
W =62.5∏ |74.66|
W =14659ft.lbs (approximately)
The work (in ft-lb) that would be required to pump all of the water over the upper rim is 14659ft.lbs

A rolling pin has a diameter of 5 inches. If Lin rolled across the table and it made 35 rotations how far did it travel?
Answers
Answer:
2.22 rotations
Step-by-step explanation:
First, have to multiply the diameter by Pi. 5 * π = 15.7
15.7 is the circumference because the formula for circumference is d * π = c (diameter=d, circumference=c)
Next, 35/15.7 is 2.22.
You divide the 35 by 15.7 because if 15.7 inches is one rotation, then you want to see how many rotations fit into 35.
The rolling pin travels a distance of 549.5 inches in 35 rotations.
What is a sphere?A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center.
Given that, the diameter of the rolling pin is 5 inches.
The circumference of the rolling pin is:
5π
= 5×3.14
=15.7
Therefore, the rolling pin covers 15.7 inches in one rotation.
1 rotation = 15.7 inches
35 rotation = 35 ×15.7 inches
35 rotation = 549.5 inches
Hence, the rolling pin travels a distance of 549.5 inches in 35 rotations.

At a sale, dresses were sold for $34 each. This price was 85% of a dress's original
price. How much did a dress originally cost?
Answers
You then do 34x15% in order to find the dollar amount that was taken off
34x15%=5.1
You can then add this dollar amount to the price paid in order to find the original price
34+5.1= $39.10
This could also be solved by doing 34+15% which is equal to 39.10
Answer:
The original price was $40
Step-by-step explanation:
let x = original price
34= 0.85x
Divide both sides by 0.85
34/0.85 = x
40 = x
