For any circle . . .Diameter = circumference/pi .

Circumference equals pi times diameter; so C = 84*pi or about 263.9.

A circumference of 263.89 cm

The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi

The circumference is approximately 527.79 units. The formula is: C = 2*Pi*r

A circumference of 263.89 cm

circumference = 84*pi

84 units x 3.1416 = 264 units (approx)

This is missing some information. For instance, it does not say what 84 is. Is it the radius, the circumference? See the link below for a step by step guide to finding a diameter.

The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi

The circumference is approximately 527.79 units. The formula is: C = 2*Pi*r

Diameter = 84 in Radius = 42 in = 3.5 feet Area of circle = pi x r x r = 3.1415 x 3.5 x 3.5 =38.483 square feet

(14/84) x 360Â° = 60Â°

With a radius of 84cm? about 528cm, or 5.28m. C=2(pi)r = 2(~3.14)(84) =~528

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.
