Todra investigates the measures of a cylinder in math class. she knows that the volume of the cylinder is 1131.0 cubic centimeters. todra determines that the length of the cylinder is 40 centimeters. What is the radius of the cylinder?
a. 1 centimeter
b. 2 centimeters
c. 3 centimeters
d. 4 centimeters
alright, you have the given which is the following:
- V = 1131.0 cm^3
- L = H = 40 cm
and we know that the general formula of the volume of the cylinder is :
\[V= \pi r^2 h\]
you have V and you have H, substitute and find R
