First find the radius:
4*pi*radius2 = 25pi square yards
Divide both sides by 4*pi:
radius2 = 6.25
Square root both sides:
radius = 2.5
Volume of the sphere = 4/3*pi*2.53 = 65.449 cubic yards to 3 d.p.

What is the area of a sector of a circle that has a diameter of 10 in. if the length of the arc is 10 in.?
The sector area works out as: 10/10pi times 25pi = 25 square in.
A sector of a circle has a central angle of 80 degree and a radius of 5 meters. Find the area of the sector?
It is: 80/360 times 25pi = 17.453 square meters rounded to 3 decimal places
What is the area of a sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches?
diameter d = 10 in radius r = 5 in arc length s = 10 in C = pi d = pi x 10 in = 10pi in s/C = 10 in/10pi in = 1/pi A circle = pi r2 = pi(5 in)2 = 25pi in2 A sector/A circle = 1/pi (cross multiply) pi A sector = 25pi in2 (divide both sides by pi) A sector = 25 in2

What is the area of a sector of a circle that has a diameter of 10 in. if the length of the arc is 10 in.?
The sector area works out as: 10/10pi times 25pi = 25 square in.
What is the volume in cubic feet of a cylinder with a diameter of 1 foot and height of 3 feet?
To find the volume of a cylinder, first you find the area of the circular base. The area of the circular base is pi * r2, which in this case is: .5 * .5 * pi = .25pi Then you multiply that by the height of the cylinder: .25pi * 3 = .75pi cubic feet That is the exact answer, the approximate answer is .75 * 3.141593 = 2.356 cubic feet
