Question

A sphere has a diameter of 22 units. What are its radius and volume?

Answer 1

The answer Is d.

radius = 11

volume = 5,572.45

Answer 2

Answer: D.  

The radius is 11 units, and the volume is 5,572.45 cubic units.

Step-by-step explanation:

We know that the volume of a sphere is given by :-

$\text{Volume}=\dfrac{4}{3}\pi r^3$, where r is radius of the sphere.

Given : The diameter of the sphere = 22 units

Then the radius of the sphere = $\dfrac{22}{2}=11\text{ units}$

Then , the volume of the sphere will be :-

$\text{Volume}=\dfrac{4}{3}(3.14)(11)^3\\\\\Rightarrow\ \text{Volume}=5572.45 \approx\text{ cubic units}$

Hence, the volume of the sphere =  5,572.45 cubic units
