The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
pi*25 = 78.5.
The area would be 78.53 squared inches. Formula: PI (x) Radius squared = Area Radius is half of the diameter of the circle. So the radius is 5 Inches. (10 divided by 2 = 5) 3.14 x 5 squared = Area ---> 3.14 x 25 = 78.53981634 Hope that helped
31.416 inches.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
Area of circle using 3.14 for pi: 3.14*5^2 = 78.5 square inches
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
pi * (radius * radius) if the diameter is 5 inches 3.14*(2.5*2.5) 3.14 * 6.25 19.625 inches
25pi 78.5 square Inches
78.5398 is the area of a circle with radius 5
Using 3.14 as Pi the area of circle is: 78.5
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
pi*25 = 78.5.
For a circle, the area is pi x radius squared. If 5 is the diameter, divide it by 2 first to get the radius. Pi is about 3.14.

If a circle has a diameter of 10 inches across it then its radius is half of 10 inches which is 5 inches.
