Question from jdkaj, a student:

cylinder a has radius 1m and height 4m. cylinder b has radius 2m and height 4m. Find the ratio of the volume of cylinder a to the volume of b


The volume of a cylinder is given by V = π r2 h cubic units where the radius is r units and the height is h units. For each of the two cylinders write an expression for the volume. Don't simplify!

Form the fraction with the volume of cylinder a in the numerator and the volume of cylinder b in the denominator. Simplify the fraction. Write the resulting fraction as a ratio.
