Question

the volume of a cylinder 3cm high and having base area 8 sq.cm is:​

Answer 1

Answer:

Let radius and height of the cylinder be r and h, respectively.

So, r=3cm and h=8cm

C.S.A. of cylinder =2πrh

C.S.A. of cylinder =2×22/7×3×8

C.S.A. of cylinder =150cm ^2

Answer 2

Given :-

• Height of cylinder = 3 cm.
• Base area of cylinder = 8 cm².

To Find :-

• Volume of cylinder = ?

Solution :-

we know that,

• Base area of cylinder = π * (radius)² .
• Volume of cylinder = π (radius)² * h => Base Area * Height .

therefore,

→ volume of cylinder = Base Area * Height = 8 * 3 = 24 cm³. (Ans.)
