As you were copying the question, did you notice the drawing alongside it ?
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.
72 centimeters of what. im gonna assume the area is 72 cm. so it would be 72 sq cm your perimeter would be around 33.94 you need to take the squared root of 72. this gives the length of one side. then multiply this number by 4 since there are four sides to a square.
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
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
Circumference = 72*pi
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
