Question

find total surface area of hemisphere whose radius is 10 cm

Answer 1

Given Radius = 10 cm.

Therefore, Total surface area = 3 × π × r × r
= 3 × 22/7 × 10 × 10
942.8 cm^2

Answer 2

$\huge \boxed {Hey Mateyy!}$

We know that, total surface area of a hemisphere =
$3\pi \: r {}^{2}$
= 3 × 22/7 × 100

= 942.85 cm^2
