Circumference 47.1 m. Find the area of the circle bounded by this circle.
| March 31, 2021 | education
The circumference of a circle is equal to twice the product of the radius of this circle and the number Pi (the number Pi is an infinite fraction, but in school practice it is customary to round this number to hundredths, that is, 3.14). Find the radius of the circle by dividing its length by twice Pi:
47.1 / 2 / 3.14 = 7.5.
The area of a circle is equal to the product of Pi and the square of the radius of the circle. The radius has already been calculated, so the area of the circle can be determined:
3.14 * 7.5 * 7.5 = 176.625.
Answer: the area of the circle is 176.625.
