Question 960833: Hi everyone.
I need some help on my math problem solving. The following problem solving are:
1. Given the circle with radius 5y centimeter, find its area. Do not approximate PI. Formula: (A=pi R^2)
2. The silo shown is in the shape of a cylinder. If its radius is 4x meters and its height is 5x^3 meters, find its volume. Do not approximate pi. Formula: (V= pi R^2 h).
Thank you very much.

------------------
You thought we wouldn't know the formula? Look up "condescension"
Area+=+pi%2Ar%5E2
Sub 5y for r
