62 x pi2 = 611.9154729 = 611.9 (1 decimal place.) It's 611.915471469109395.
that is 14,519.4 squared
Area is pi times the radius, squared. And circles are two-dimensional. There is no volume. But for cylinders, the area is pi times the radius squared, times two, times the height.
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
circumference is 2 times pi times radius area is pi times readius squared
pi times the radius squared pi r squared
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
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.
Circumference = pi (3.14) times the diameter (radius times two) Area = pi (3.14) times the radius squared
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
The area of a circle is: pi times radius squared
Since the formula for the area of a circle is pi times the radius squared and the formula for the circumference is two times pi times the radius, you would find the circumference by first dividing by pi. This would give you the radius squared. Find the square root of this value. This will give you the length of the radius. Take this length and multiply it by two times pi.
