Question

How can I find the volume of a cylinder which diameter is 10cm, and whose height is 12cm, and find the cross section?​

Answer 1

Volume=943 cm^3 Cross section area=79 cm^2

Explanation:

volume of a cylinder is
`\pi r^(2) h`

so 10/2=5 5^2=25*12=300*pi is about 942.477 or 943 cm^3

to find the area of the cross section, on just needs to find the area of the face of the cylinder. so pi times 5^2=pi times 25=78.540 or 79 cm^2
