3)

The volume is about 3.5^2 *3.14(pi*r^2) because the diameter is 7cm so the volume is 3ish^2*3ish so the answer is 9^3 = 27

4)

You would need to know the area of a circle if you wanted to put a rocket into space, you would need to know how much fuel is in the tank

5)

a)

the radius is 2.3, so the answer is 2.3^2*pi = 5.29pi

b)

5.29pi/2 = 2.645pi
