Because a circle does not have length times width so pi is in it's place.

Area of a circle is: pi times radius squared
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Area equals pi times the radius squared.
no, the area of a circle equals pi times the radius squared or circumference times diameter over four.

The area of a circle equals pi x r squared or A = pi x r2 A = area of circle pi = approximatley 3.14 r = radius

Using 3.14 as Pi the area of circle is: 0
The formula for the surface area of a circle is pi times the square of the radius. It is represented as A equals pi times r squared.
You will get pi since area of a circle equals pi* times radius squared....by Mona Martinez
The area equals pi times the radius squared. The radius is half the diameter. The area of the circle = (9.75/2)2(3.14) = 74.6240625 or about 74.6 units squared.
Area of a circle = pi*radius2 measured in square units
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
