What is the area of the circumference is 64?
As 2πr=64π i.e. r=64π2π=642=32 , Hence, area is π(32)2=1024π .
How do you find the radius of a 64?
1 Answer
- π is the ratio between a circle’s circumference and diameter. In other words, C=πd=2πr.
- Plug in your information: 64=2πr.
- 642π=r.
- 32π=r.
- r≈10.186.
How do you find the radius of a circle with the area and circumference?
How to find the area of a circle from the circumference?
- Divide the circumference by π.
- Divide the result by 2 to get the circle’s radius.
- Multiply the radius by itself to get its square.
- Multiply the square by π, or 3.14 for an estimation.
- You found the circle’s area from the circumference.
