Question

Find the total surface area of a hemisphere of radius 10 cm. (Use π = 3.14)​

Answer 1

Answer:

Step-by-step explanation:

Hemisphere:

When

a plane through the centre of a sphere divides the sphere into 2 equal parts

then these two equal parts are called hemisphere.

===========================================================

Given: radius(r) = 10 cm

Total surface area of hemisphere = 3πr²

= (3 × 3.14 × 10 ×10)

= 9.42×100

= 942 cm²

Hence, the total surface area of a hemisphere

is 942 cm²
