The surface area of a sphere is (4 pi) x (radius of the sphere)-squared.We're not completely sure of what a "90' sphere" is. If you're saying that thesphere's diameter is 90-ft, then its radius is 45-ft, and its surface area is(4 pi) x (45-ft)-squared = 25,446.9 square feet, or 2,827.4 square yards. (both rounded)
A 45-foot diameter circle has an area of 1,590.4 square feet.
188.13 square meters.
You will need a minimum of 160 feet of fencing for the perimeter of that size area.

To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.

The total area of a floor that measures 45 feet by 24 feet is: 45 x 24 = 1080 square feet.
105 x 45 x 3 ie 14175 sq ft
It is 105 feet * (45 yards*3) = 105 ft *135 ft = 14175 square feet.
The volume of an area 24 feet round and 45 inches deep is: 1,700 cubic feet.
A 45-foot diameter circle has an area of 1,590.4 square feet.

If you were to fence an area that was 45 ft x 80 ft, you'd need approximately 3600 ft².
Area = 139.36 ft2
You will need a minimum of 160 feet of fencing for the perimeter of that size area.
