What is the volume of the figure in terms of pi?

1539.38

Step-by-step explanation:

this can be figured out as an entire cylinder and then take 1/2 of that

area of a circle of 7 cm

area =

area = 153.938

volume = 153.938 * 20

volume = 3078.7608

and take 1/2 of that to find volume of the half cylinder

3078.7608 / 2 = 1539.38

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
