Asked by Andrea

a circular cylinder has a base with a radius of 7.5 cm. and a height of 12 cm. a rectangular prism has a square base and height of 8.0 cm. if the cylinder and the prism have equal volumes, what is the length of the base of the prism to the nearest tenth?
Answered by PsyDAG
The volumes are equal, so the equation below fits. Insert values and solve for L.

π*r^2*h = h*L^2

16.3 is the length of the base rounded to the nearest tenth.
3.14 x 7.5 x 7.5 x 12 = 2119.50

16.28 x 16.28 x 8 =2,120.3
