A circle has the circumference 28.26cm. What is the area of the circle? use PI as 3.14.
i am confused in how to even solve with the circumference to get the area. Please help
Since c = 2pi r, r = c/2pi
a = pi r^2 = pi(c/2pi)^2 = c^2/4pi
so, plug in your value for c.
To find the area of a circle using the circumference, you can use the following formula:
Area = (Circumference^2) / (4 * π)
Given that the circumference is 28.26 cm and π is 3.14, we can substitute these values into the formula to find the area:
Area = (28.26^2) / (4 * 3.14)
= 795.4756 / 12.56
= 63.36 cm^2
Therefore, the area of the circle is approximately 63.36 cm^2.
