Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16 inches, radius = 8 inches, and area = (pi) (8)2 = 201.062 square inches (rounded)
Area of the circle in square inches = pi*82
Using 3.14 as Pi the area of circle is: 200.96
Radius of circle: 16/2 = 8 inches
Area = pi * radius * radius radius = diameter / 2 radius = 16/2 = 8 Area = 64 * pi Area 201.062 inches2
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16 inches, radius = 8 inches, and area = (pi) (8)2 = 201.062 square inches (rounded)
The radius is 8 inches.
Area of the circle in square inches = pi*82
Using 3.14 as Pi the area of circle is: 200.96
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
A circle with a radius of 8 inches has a circumference of 50.27 inches.
diameter = 8 inches so the radius will = 4 inches area of a circle = pi*radius2 area = 50.26548246 or 50 square inches to the nearest square inch.
r = 8 inches d = 16 inches
If the circle has a diameter of 8 inches, it's 50.265 square inches. If the circle has a radius of 8 inches, it's 201.06193 square inches. In the odd case that the circle has a circumference of 8 inches, it's 5.09296 square inches.
Radius of circle: 16/2 = 8 inches
Area = pi * radius * radius radius = diameter / 2 radius = 16/2 = 8 Area = 64 * pi Area 201.062 inches2
8 inches; the diameter of a circle is twice its radius.
