8. If the area of the base of the cylinder is
90 sq cm and its height is 12 cm, then find
its volume​

Answer 1

Answer:

πr^2=90c^2

H=12cm

Volume=πr^2h

=90x12=1080cm^3

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Given :-

Area of base of cylinder = 90 cm²

Height of cylinder = 12 cm

To Find :-

Volume of the cylinder

Formula to be used :-

Volume of Cylinder = πr²h

Solution :-

⇒ Area of base of cylinder = πr² = 90 cm²

Putting all the values, we get

⇒ Volume of Cylinder = πr²h

⇒ Volume of Cylinder = 90 × 12

⇒ Volume of Cylinder = 1080 cm³

Hence, the Volume of the cylinder is 1080 cm³.

Extra Information :-

Surface Area of a Cylinder = 2πr (r + h)

Curved Surface Area of a Cylinder = 2πrh

Volume of a Cylinder = πr²h
