Area of circle = pi*(radius)2
pi*radius2 is the formula for finding the area of a circle.
The formula for finding the area of any circle is pi*radius2..
Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
The area is 5,024 ft2. The formula for finding the area of a circle is: A = pi * r2 A for area. The r is for the radius. A = 3.14 * 40 ft2 A = 3.14 * 160 ft2 A = 5,024 ft2
Area of a circle = pi*radius squared
Area of a circle = pi*radius2
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
Using 3.14 as Pi the area of circle is: 1017.36
Pi * R squared, where R is the radius of the circle in question
To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius
pi*radius2 is the formula for finding the area of a circle.
It is the formula for finding the area of a circle which means: pi times radius squared
It is the formula used in finding the area of a circle which is pi times radius squared
The formula for finding the area of a circle is A= pi r2. Square the radius then multiply it by pi. For your instance, 2.5 squared is 6.25. 6.25 x pi= 19.634... The area of a circle with the radius of 2.5 is 19.634...
