How many square feet are in a 30 foot diameter circle?
The formula is pi*r^2, 30/2 is 15ft. 15x15x3.14159 is 706.86 sq ft
What is the volume of a cylinder that has 15ft diameter and stands 22ft. tall?
The volume of this cylinder is 3,887.7 cubic feet.
A vertical tank is 50 ft tall with a diameter of 7ft product level is 15ft what is the volume of product in the tank?
The volume would be pi*r^2*height =pi*(3.5ft)^2*15ft which gives an answer of 577.2676501 cubic feet.
If a circle is 15ft around how many sq ft is it?
We could say the circumference of the circle is 15 feet and you want the area. The formula for area of a circle is usually given as Pi times the radius squared but we don't have the radius ( or at fist it seems we don't) The circumference is 2x Pi x radius and this is 15 so the radius is 15/2Pi Now we have what we need to use the formula. The area is Pix (15/2Pi)^2=15^2/4Pi This is 225/Pi and using 3.14 as an approximation to Pi the are is about 17.914 which we can round to 18 square feet if you want.
What does 15ft equal?
180 inches
