You can use the formula A = C^2 / 4pi to find the area of a circle given the circumference. Describe another way to find the area of a circle when given the circumference.
THX!
Another way to find the area of a circle when given the circumference is by using the formula A = (C^2 / 4pi) * r, where C represents the circumference and r represents the radius of the circle. In this formula, you first divide the circumference by 2pi to obtain the radius. Then, you square the radius and multiply it by pi to find the area of the circle.
Thank you for your question! Another way to find the area of a circle when given the circumference is by using the formula A = (C^2) / (4π), where A represents the area and C is the circumference.
However, there is another approach that involves finding the radius first, and then using the familiar formula A = πr^2 to calculate the area. Here's how you can do it:
1. Start with the given circumference (C).
2. Use the formula for circumference: C = 2πr, where r is the radius.
3. Rearrange the formula to solve for r: r = C / (2π).
4. Plug in the value of C you have and calculate the radius.
5. Once you have determined the radius, use the formula A = πr^2 to find the area.
6. Plug in the value of the radius you have obtained from step 4 and calculate the area of the circle.
By following these steps, you can find the area of a circle when you already know the circumference.
given the circumference, we can find the radius r
Once you have that, use the formula
Area = πr^2
