A manufacturer of tin cans wishes to construct a right circular cylindrical can of height 20 centimeters and capacity 2600 cm^3 (see the figure). Find the inner radius r of the can. (Round your answer to one decimal place.)

Question

r = cm

Answer 1

V=πr^2h

2600 = 3.14 * r^2 * 20

2600 = 62.8 * r^2

2600 / 62.8 = r^2

41.40127 = r^2

6.4 = r
