The area of a cylinder is v=pi(r^2)(h)
a.) The old silo has a diameter of 10 ft, if we take half of 10 we get 5 ft which is the radius. r=5... The height of the old silo is 25 ft. h=25
Here is the work:
v=pi(5^2)(25)
v=pi(25)(25)
v=pi(625)
v=1963.5
b.) The new silo has a diameter of 15 ft, if we take half of 10 we get 7.5 ft which is the radius. r=7.5... The height of the new silo is 30 ft. h=30
Here is the work:
v=pi(7.5^2)(30)
v=pi(56.25)(30)
v=pi(1687.5)
v=5301.4
c.) The new silo is 270 times greater than the old silo because 5301.4/1963.5 = 270.06
