Question:

I dont get geometry help me please?

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.

Answer:

A cylinder, if you take a cross section, is a circle. You can think of it as a tall circle. So, you find the area of the circle, then multiply it by the height to find the volume.
The Cylinder Volume Formula is pi * radius2 * height Then Pi = 3.14159 Radius = 301 feet and Height = 96 Feet then The Silo can Hold 3.14159*301^2*96 feet^3 = 27324594,77 feet^3 or = 27324594,77 CUBIC FEET
All you need to do is apply the formula for the area of a cylinder. If you can't remember that, remember that the area of the circle = pi * radius^2, or in this case ~285,000 sq feet. Then multiply this by 96 (or by 100 to estimate) to get ~28,500,000 cubic feet.
