A cylinder has a radius of 3 cm and a height of 5 cm. a. What is the volume of the cylinder? answer in pi, cm3
b. What is the volume of the cylinder when its height is tripled? answer in pi, cm3
c. What is the volume of the cylinder when its height is halved? answer in pi, cm3

Will give 50 points if answered correctly, I don't understand this, please help

Step-by-step explanation:

a. So in order to find the volume of a cylindar you need to know the formula which is V= r^2h(pi)

So you plug the info in V= (3)^2 * (5) * pi >            V= 9 * 5 * pi

45pi cm^3 ( the label is cm ^3 because we are finding volume)

b. When the height is tripled you multiply it by three so

V= (3)^2 * (5)(3) * pi

135pi cm^3

c.

Now you are halving the height so you multiply it by 1/2

V= (3)^2 * (5)(1/2) * pi

22.5pi cm^3

a. 141.3cm^3 b. 1060.2cm^3 c.?
