The area of a circle that has diameter of 3 cm is: 7.069 cm2
The area of a 3-inch diameter circle is about 7.068 square inches.
7.065
A 3 centimeter diameter circle has an area of 7.068 cm2
Divide the area by Pi to get the diameter.
7.0686 square feet for a 3-foot diameter circle.
Use the formula area = pi x radius2. The radius is half the diameter.
The diameter of a circle with an area of 37.68 is 6.92
Area of a circle = pi x (radius)2And radius = diameter / 2 = 3/2 = 1.5So, area = pi x (1.5)2 = 7.06858347 cm2
1) the diameter of a circle = 2*its Radius. 2) the circumference of a circle = Pi*its diameter (where pi = approx 3.14). 3) the area of a circle = Pi*its radius squared.
Using 3.14 as Pi the area of circle is: 28.259999999999998
The area of a circle with the diameter of 3m is 7.069 m2
