7 foot circumference X 12 inches/foot = 84 inches in circumference
The volume of a cylinder is pi*(radius)^2*height. We are not given the radius here, but we know the circumference. Circumference is 2*pi*radius. So radius is equal to the circumference/(2*pi). We can then substitute this into the equation for volume to get: V=pi*(circumference/(2*pi))^2*height=(circumference)^2/(4*pi)*height._________________________________________________________________For your problem we have circumference=84 inches and height=32 inches. So:(84 inches)^2/(4*pi)*32 inches=7056 square inches/(4*pi)*32 inches=1764 square inches/pi*32 inches=56448 cubic inches/pi=17967.9564553 cubic inches which is about 17968 cubic inches.
(14/84) x 360° = 60°
You can convert 7 feet 4 inches to inches. 1 foot = 12 inches 7 feet = 7 x 12 inches = 84 inches 7 ft 4 in = 84 + 4 in = 88 in
about 12.57 inches
7 foot circumference X 12 inches/foot = 84 inches in circumference
The circumference of a circle is calculated using the formula C = π*d, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 84 inches. Plugging this into the formula, we get C = 3.14159 * 84 = 263.89356 inches. Therefore, the circumference of a circle with an 84-inch diameter is approximately 263.89 inches.

Inches and inches are the same unit of measurement. Therefore, 84 inches is equal to 84 inches.
Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches. Circumference = 72.22 inches => radius = circumference/(2*pi) = 11.49 inches and so area = pi*radius2= 415.05 sq inches.
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
For any circle . . .Diameter = circumference/pi .
