Question 204154

Find the volume. Round to the nearest whole number, if necessary.
Cylindrical grain silo with hemispherical top. Where the heighth of the cylinder is 11 ft. and the diameter is 62 ft
.
Volume of cylinder:
(pi)r^2h
= (3.14)31^2*11
= 33192.94 cubic feet
.
Volume of hemisphere:
(1/2)(4/3)(pi)r^3
= (1/2)(4/3)(3.14)31^3
= (4/6)(3.14)31^3
= 62362.49 cubic feet
.
Total = 33192.94 + 62362.49 = 95555.43 = 95555 cubic feet
