Answer:
The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 π r2 = 1062.
Step-by-step explanation:
Answer:
K = (2πr2) + (πr2) = 3πr
Step-by-step explanation:
K = (2πr2) + (πr2) = 3πr Heres something that might help.
