78.5 square Inches
pi * (radius * radius) if the diameter is 5 inches 3.14*(2.5*2.5) 3.14 * 6.25 19.625 inches
A circle with a radius of 5 units has an area of 78.54 square units.
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
Square footage is called "area". To find the area of a circle: A = pi x r2 So for a circle with a 10-inch diameter (which means a 5-inch radius): A = 3.141593 x (52) So the area = 78.54 inches
90 square inches
The area of a circle with a 5-inch diameter is: 19.63 square inches.
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
The area of a 5-inch circle is: 19.6 square inches.The area of a 4-inch circle is: 12.6 square inches.The area of the 5-inch circle is 55.6% larger than the 4-inch circle

A=pi times R squared If the radius is 5, the area is 25pi
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
