Question

find the total surface area of a hemisphere of or radius 10 cm(use
$\pi = 3.14$


​

Answer 1

Answer:

942 cm²

Step-by-step explanation:

Radius of hemisphere = 10 cm

Total Surface area of hemisphere = 3πr² = 3*3.14*10*10 = 3*314 = 942 cm²

Answer 2

942 cm²

Radius of hemisphere =10 cm

total surface area of hemisphere =

$3\pi \: r {}^{2}$

=3×3.14×10×10=3×314

=942cm²
