Well, see, that sketch is actually part of the question; anybody who wants to
try and answer it needs to see that drawing.
(72 pi) inches = 226.19 inches (rounded)
Assuming it is a circle, it is about 63.8 inches, a square would be 72 inches.
The perimeter of a square is calculated by adding the lengths of all four sides together. Since all sides of a square are equal in length, you can multiply the length of one side by 4 to find the perimeter. In this case, if the square is 72 centimeters on each side, the perimeter would be 72 cm x 4 = 288 cm.
Diameter = 2 x (radius)Circumference = (pi) x (diameter) = (pi) x (2 x 72) = 144 pi = 452.39-ft (rounded)
The length of the rectangle is 27 meters and the width is 19 meters.
It is: 72-lenghth of major arc = length of minor arc
17
15 in
The arc represents 1/5 of the circumference (72 = 360/5) so the full circumference is 5 x 18.75 ie 93.75, which is 2 pi x the radius. The radius is therefore 46.875/pi, just over 14.9.
If this is a central angle, the 72/360 x (2xpix4) = 5.024
Circumference = 72*pi
Circles don't have "length", however: C = 2*pi*r d = pi*r Thus, the radius of a circle can be found by dividing the Circumference (C) by (2*pi): 72 cm / (2*pi) = 11.459 cm
72" radius = 452 25/64 " circumference
A circle with a radius of 72 inches has a circumference of 452.39 inches.
To calculate the diameter from the circumference, divide the circumference by pi - π 6' = 72 inches. 72 / π = 22.9 inches
Circumference = 72*pi
Since π is the ratio between the diameter and the circumference, Diameter = 72 in /π = 22.92 in
