Question

find the total surface area of hemisphere of radius 10 cm. pi =3.14

Answer 1

TSA of hemisphere = 3πr²
r = 10cm

TSA = 3 * 3.14 * 10 * 10
= 942cm²

Answer 2

hi!
here is your answer!

r =10cm

We know that,

Total surface area of hemisphere
$= 3 \pi {r}^{2}$

$= 3 \times 3.14 \times {10}^{2}$


$= 3 \times 3.14 \times 100$

$= 3 \times 314$

$= 942 {cm}^{2}$

Therefore,
The total surface area of hemisphere is 942 sq.cm
