Question

If the sphere shown above has a radius of 19 units, then what is the approximate volume of the sphere?
A.
9,145.33 cubic units
B.
1,444 cubic units
C.
11,431.67 cubic units
D.
4,572.67 cubic units

Answer 1

Volume of a sphere = \(\dfrac{4}{3}\pi r^3\)

where r is your radius

and they told you r = 19

so plug that in and solve for the volume

Answer 2

volume = \(\dfrac{4}{3} \times \pi \times (19)^3\)

volume = ??
