A circle with a radius of 11m has an area of ~380.13 m2
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.
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
Using 3.14 as Pi the area of circle is: 379.94
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 of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a radius of 11 miles, the area is ( A = \pi (11)^2 = 121\pi ) square miles. Using ( \pi \approx 3.14159 ), the exact area is ( 121\pi ) square miles, or approximately 380.132 square miles when calculated numerically.
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
