The radius is 11.
Radius, r = diameter / 2 Then circumference = 2*pi*r and area = pi*r*r
5.5 feet.
The radius is equal to 1/2 the diameter. 11 divided by 2 =5.5
The area of an 11-inch diameter circle is: 95.03 square inches.
A circle with a radius of 11 inches has an area of 380.13 square inches.
The radius of a circle with an area of 380 sq inches is 11 inches.
Using 3.14 as Pi the area of circle is: 379.94
A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
The area of a circle is: pi times radius squared
A = 380 square feet.
Area of the circle: pi*11^2 = 121*pi square units
area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2
5.5 is the radius.
Using 3.14 as Pi the area of circle is: 0
the area can not be cubed. the area is always squared. volume is cubed. the formula for area is pie multiplied by radius squared. your formula for your circle is... A = 121pi in2 the radius in your circle is 11 inches the formula for circumference is two times pi times the radius C = 2 * (3.14159) * 11 your answer is 69.11498in
Area of the circle: pi*11^2 = 121*pi square units
