Question

A silo shaped as a cylinder with a diameter of 4.50 meters and a height of 9.60 meters is used to store grain. How much grain, in cubic meters, is stored in the silo if it is three-fourths ful?​

Answer 1

458.044209 (457.81200 for 3.14) m^3 of grain

Explanation:

First figure out the area of the base using A = pi r^2

A = pi 4.5^2

A = 20.25pi

A = 63.6172512 (63.585 for 3.14)

3/4 of 9.6 is 7.2

A * 7.2 = 458.044209 (457.812 for 3.14)
