Answer:
452.839cm
Step-by-step explanation:
in order to find the volume of a cylinder is to use this formula:
V= πr^2h
So the equation says the radius of the cylinder is 4cm and the height is 9cm and pie is equivalent to 3.14, so lets put this information in the formula:
V= (3.14)(4)^2(9)
so first we multiply 4 to the second power:
4^2 = 16
then multiply it by 3.14:
16 * 3.14 = 50.24
then multiply it by the height which is 9:
50.24 * 9 = 452.839
so the volume of the cylinder is 452.839cm
hope this helps you!!
