Math Problem Statement

What is the volume of this sphere? the radius is 36

Use β€‹πœ‹ β‰ˆ 3.14 and round your answer to the nearest hundredth.

Solution

The volume VV of a sphere is given by the formula:

V=43Ο€r3V = \frac{4}{3} \pi r^3

where rr is the radius of the sphere and Ο€\pi is approximately 3.14.

Given that r=36r = 36, we can plug this into the formula:

V=43Γ—3.14Γ—(36)3V = \frac{4}{3} \times 3.14 \times (36)^3

First, calculate 36336^3:

363=36Γ—36Γ—36=46,65636^3 = 36 \times 36 \times 36 = 46,656

Now, plug this value back into the formula:

V=43Γ—3.14Γ—46,656V = \frac{4}{3} \times 3.14 \times 46,656

Calculate the result step by step:

V=43Γ—146,497.92=4Γ—146,497.923=585,991.683=195,330.56V = \frac{4}{3} \times 146,497.92 = \frac{4 \times 146,497.92}{3} = \frac{585,991.68}{3} = 195,330.56

So, the volume of the sphere is approximately 195,330.56 cubic units.
