A. $1648.5\ ft.^3$

3. $33,493.3\ cm^3$

Step-by-step explanation:

A. Given: Height of cylinder = 21 ft.

Diameter=10 ft

then Radius = $\dfrac{10}{2}=5\ ft.$

The volume of cylinder is given by :-

$\text{Volume}=\pi r^2 h\\\\\Rightarrow\ \text{Volume}(3.14) (5)^2(21)\\\\\Rightarrow\ \text{Volume}=1648.5\ ft.^3$

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

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

Given : The radius of the sphere =20 cm

Now, the volume of the sphere will be :-

$\text{Volume}=\dfrac{4}{3}(3.14) (20)^3\\\\\Rightarrow\ \text{Volume}=33,493.333\approx33,493.3\ cm^3$
