pi = 22/7
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
divide the circumference by pi (3.1416) and divide the product by two that will give you the radius
(pi)(1/pi)=1.4396 ...
the same as pi squared, which is 9.86960440109
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
The circumference of a circle is the product of the diameter x pi.
Area of a circle = pi*radius2
( pi ) x ( 3/pi ) = 3
pi
(pi) x (1/pi) = 1

That would be the circumference of the circle.
The general formula for area of a circle is A=(pi)r2, the product of pi and the square of the radius. In this instance, the area equals pi X 92 = about 254.47.
In any circle, the product of pi and the diameter will be the circumference. That is because pi is the ratio of the diameter of a circle to its circumference. Here is the equation: c = pi x d
The number is ' pi ' = 3.1416 (rounded)
The volume would be pi*r^2*height =pi*(3.5ft)^2*15ft which gives an answer of 577.2676501 cubic feet.
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
