The surface area of a sphere can be found with the formula 4pi * r2. Assuming the hemisphere is exactly half of a sphere, the surface area of a hemisphere can be found using the formula A = 2pi * r2 + pi * r2
Which can be written as A = pi(3r2)
942cm/pi = 3r2
314cm/pi = r2
r = 10cm (approximately)
The radius of the hemisphere is approximately 10cm.
