Janine made a cylindrical vase in which the sum of the lateral area and area of one base was about 3000 square centimeters. The vase has a height of 50 centimeters. Find the radius of the vase. Explain the method you would use to find the radius.

Answer 1

the area is

a = πr^2 + 2πrh
So,

πr^2+100πr = 3000
r^2+100r = 955
r = 8.779

So, r is about 9
