Since the area equals pi times the square of the radius, the radius must be the square root of (the area divided by pi). I got that by dividing both sides of the equation by pi then taking the square root of both sides.
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
Area of a circle equals pi (3.14) times the radius squared.
Rewrite the above program so that the program accepts any value for the radius then recalculate the area of the circle.
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle is pi * radius2. If you already have the radius squared, you just have to multiply that by pi.
The formula for the area of a circle is pi x radius x radius or pi(r2).
Area of a circle equals pi (3.14) times the radius squared.
Rewrite the above program so that the program accepts any value for the radius then recalculate the area of the circle.
You would need to include the radius to be able to determine the area.
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
Radius = 34.99112712 units Divide 3846.5 by pi and square root the result.
