Question

What is the volume of a cylinder 7cm wide and 10cm high

Answer 1

V = pir2h

Diameter = 7 and height = 10

so r = d / 2

V = pi3.5*2(10)

V = pi12.25(10)

V = pi122.5

V = 3.14 * 122.5

V = 384.65

Answer 2

Answer:

V =384.65 cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter is 7 cm, so the radius is d/2 = 7/2 =3.5

V = (3.14) * (3.5)^2 *10

V =384.65 cm^3
