The formula for the area of a circle is:
Area=π∗(Radius)2\text{Area} = \pi * \text{(Radius)}^{2}
The radius is the distance from the center of the circle to the edge:
radius
In this problem, the radius of the circle is 1010

To find the area of the circle, square the radius:
(10)2=100\left(10\right)^{2} = 100
Now multiply by π\pi. The number π\pi is approximately equal to 3.14.
Area=π∗(Radius)2\text{Area} = \pi * \text{(Radius)}^{2}
Area=3.14∗100\text{Area} = 3.14 * 100
Area=314\text{Area} = 314
