The surface area of sphere = 3844 m^2 radius = r surface area of sphere = 4×22/7 ×r^2 3844 = 4×22/7×r^2 3844×7/4=r^2 961×7 = r^2 6727 = r^2 r = under root 6727 r = 82.01 m

radius = r
surface area of sphere = 4×22/7 ×r^2
3844 = 4×22/7×r^2
3844×7/4=r^2
961×7 = r^2
6727 = r^2
r = under root 6727
r = 82.01 m
