Question

I only need help with the last one the circle one to be pacific. I need help by tonight so I can get this done.

Answer 1

Answer:

$V = 997.8 {cm}^{3}$

Step-by-step explanation:

The last one is spherical

The volume of a sphere is given by:

$V= \frac{4}{3} \pi \: {r}^{3}$

From the diagram, the the radius is r=6.2 cm.

We substitute to get:

$V= \frac{4}{3} \times 3.14\: \times {6.2}^{3}$

This evaluate to;

$V = 997.8 {cm}^{3}$
