Question

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

Answer 1

Answer:

TSA of hemisphere= 3πr^2

=3×3.14×10×10cm

=314×3

= 942 cm^2

Hope it helps

Answer 2

Answer:

Given, radius = 10

Total surface area of hemisphere:

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

$= 314 \times 3$

$= 942$
