Площадь круга равна:

S = пR² = 3,14 * 17,86² ≈ 1001,6 см²

Answer 2

Calculation of the Area of a Circle

To calculate the area of a circle, we can use the formula:

Area = π * r^2

where π is the mathematical constant pi (approximately 3.14) and r is the radius of the circle.

Given that the radius of the circle is 17.86 cm, we can substitute this value into the formula to find the area.

Area = 3.14 * (17.86)^2

Calculating this expression, we find that the area of the circle is approximately 1002.78 square centimeters.

Please note that the value of pi used in this calculation is an approximation. The exact value of pi extends infinitely and is approximately equal to 3.14159. However, for most practical purposes, using the approximation 3.14 is sufficient.

I hope this helps! Let me know if you have any further questions.
