# Find the total surface area of a hemisphere of radius 10 cm. (Use $${\pi}$$ = 3.14)

We know that,

total surface area Of hemisphere
= CSA of hemisphere + Area of circular end of hemisphere
= $$2 {\pi} {r}^2 + {\pi} {r}^2$$
= $$3 {\pi} {r}^2$$
= [$$3 × 3.14 × (10)^2 {cm}^2$$]
= 942 $${cm}^2$$

Therefore, the total surface area of such a hemisphere is 942 $${cm}^2$$.
