Question

Q7. The volume of a cylinder is also equal to area of dash and dash​

Answer 1

Answer:

Let r be the radius of the base of the cylinder, h be the height and V be the volume of the cylinder.

h=r          ...given

Volume of cylinder (V)=πr2h

∴V=πr2×r

∴V=πr3

Answer 2

Step-by-step explanation:

The formula for the volume of a cylinder is V=Bh  or  V=πr2h .

The radius of the cylinder is 8 cm and the height is 15 cm.

Substitute 8 for r and 15 for h in the formula V=πr2h .

V=π(8)2(15)

Simplify.

V=π(64)(15)≈3016

Therefore, the volume of the cylinder is about 3016 cubic centimeters.
