A cyndrical silo is 96 feet high and has a base with radius 301 feet. Esimate the number of cubic feet of grain the silo can hold.
The volume of a cylinder is the area of the base times the height. I leave the calculation to you.
volume of a cylinder is defined as pi x radius squared x height. so the volume would be approximately 27,324,617.857 cubic feet.
The volume of a cylinder is the area of the base times the height. The base is a circle of radius 301. Go calculate.
Are you sure the radius is 301 feet? That would be a diameter of 602 feet, awfully doggone big. Anyhow, the answer is Pi times (radius squared) times height. But you said ESTIMATE, not calculate, so mentally you can do 300 times 300 = 90,000 times 3 = 270,000 times 100 = 27,000,000 cubic feet. That's a rough estimate, done mentally, which MAY be the point of the exercise. Do the math to get the exact answer.
The number of cubic feet the cylinder will hold is also known as the volume of the cylinder. The formula for the volume of a cylinder is Pi x Radius Squared x Height. You have Volume = 3.14 x 301^2 x 96 = cubic feet of grain 3.14 x 90601 x 96 = cubic feet of grain 284631.4359997535 x 96 = cubic feet of grain 27324617.855976336 = cubic feet of grain
