find the radius of a hemisphere whose surface area is 1848 meter square
.
definition of a hemisphere:
A half of a sphere
.
Sphere Surface = 4pr^2
where
p is pi
r is radius
.
hemisphere surface = (1/2)4pr^2
hemisphere surface = 2pr^2
.
1848 = 2pr^2
1848 = 2(3.14)r^2
924 = (3.14)r^2
294.267515 = r^2
17.15 meters = r
