To find the area of the circle pi*radius*squared and subtract the area of the figure inside
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
Since area of a circle = πr^2, a circle with r=1 would have an area of π.
Area of a circle = pi*radius2
The area of a circle with a radius of 10 km is πr^2, where r is the radius. In this case, the area would be approximately 314.16 square kilometers.
10km = 10km 11km - 1km = 10km 1000m = 10km 10km/h * 1h = 10km
10km to 100km range
10km = 1,000,000cm, so 10km is the biggest.
10km is about 10,936 yards.

Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Using 3.14 as Pi the area of circle is: 0
