Question

the area of the base of a solid hemisphere is 36cm². it's curved surface area is​

Answer 1

Given:- Area of base of hemisphere = 36 cm^2

To Find:- Curved Surface Area of hemisphere.

Solution:-

$\pi {r}^{2} = 36 \\ {r}^{2} = \frac{36}{\pi}$

The Curved surface area(C.S.A) of hemisphere is given by,

$2\pi {r}^{2}$

So, C.S.A = 2π*36/π = 72 cm^2
