16ft = 2πr π = 3.142 (a constant) -------- r is the radius 16/2π = r r = 16/6.284 r= 2.54 feet

The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.

The formula for the volume of a cylinder is V = Ï€r2h, where Ï€ is pi (3.14159), r is radius, and h is height. To get the radius, you divide the diameter by 2. So the radius is 16ft/2 = 8ft. Now you can plug your known values into the formula: V = Ï€r2h = (3.14159)(8ft)2(10ft) = 2010.6ft3

By outside distance, do you mean the circumference? The circle has a diameter of 16ft, its circumference is 3.14*16=50.24ft

Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16-ft, radius = 8-ft, and area = (pi) (8)2 = 201.062 square feet (rounded)

The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.

16ft. 16ft.

16ft x 18ft= 288 ft^2

40ft + 40ft + 16ft + 16ft = 112 ft

If they are 16ft x 16ft, two will be more than enough.

There are exactly 32 square yards in 16ft X 18ft
