Question

Can anyone please help me? :)

Answer 1

I think it is 20 pi units.

Explanation:

Given:

h= 5 units

Base area (its base is a circle. And we know, Area of the circle is pi*r^2 )

So now,

Volume of cylinder= pi*(r)^2 * h

= (pi*r^2) * h (the base area is given as 4 pi, so we substitute it )

= 4pi* 5

= 20 pi units.

Hope it helps........
