Why are there two formulas to calculate the circumference of a circle?
They are: 2*pi*radius or as diameter*pi
What are the formulas for circumference and area of circles?
The circumference ( C ) of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the circle. The area ( A ) of a circle is given by the formula ( A = \pi r^2 ). In both formulas, ( \pi ) (pi) is a constant approximately equal to 3.14159.
The area of a circle is 12.56 square miles what is the circle's circumference?
To find the circumference of a circle given its area, we can use the formulas for area (A = \pi r^2) and circumference (C = 2\pi r). Given the area (A = 12.56), we can solve for the radius (r): (r = \sqrt{\frac{A}{\pi}} = \sqrt{\frac{12.56}{\pi}} \approx 2) miles. Then, we can calculate the circumference (C = 2\pi r \approx 2\pi(2) \approx 12.57) miles. Thus, the circle's circumference is approximately 12.57 miles.

How much is 26 meters in circumference?
Circumference is a measure of the distance around a circle. If you have a circle with a circumference of 26 meters, that means the total distance around the edge of the circle is 26 meters. If you're looking for a diameter or radius based on this circumference, you can use the formulas: diameter = circumference/π (approximately 8.27 meters) and radius = diameter/2 (approximately 4.14 meters).
