radius = 32/(2*pi) inches
A circle with a radius of 32 cm has a circumference of 201.06 cm.
Circumference = (2 radius) X 3.14
Diameter = 32pi/pi = 32 ft Radius = 32/2 = 16 ft
Radius: 201.1/(2*pi) = 32 units to the nearest integer
radius = 32/(2*pi) inches
A circle with a radius of 32 cm has a circumference of 201.06 cm.
201.06 in
Circumference = (2 radius) X 3.14
A circle with a radius of 16 inches (32/2) has a circumference of 100.53 inches.
r = 5.09 feet
32 pi = 100.531 (rounded)
Diameter = 32pi/pi = 32 ft Radius = 32/2 = 16 ft
Radius: 201.1/(2*pi) = 32 units to the nearest integer
Divide that by (2 x pi).
4*pi or 12.56
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.
