Answer:
The volume of sphere is .
Step-by-step explanation:
We have,
Radius of a sphere is 18 units.
It is required to find the volume of sphere.
The formula of the volume of sphere in terms of radius is given by :
Plugging all values in above formula
So, the volume of sphere is .
well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus
V= 32.5ℓ (m^3)
when ℓ= 8.4 m , V= 273 m^2
