he radius of a circle is 6 cm . Find its area to the nearest whole number.

To find the area of a circle, you can use the formula A = πr², where A is the area and r is the radius. Plugging in the radius of 6 cm, you get A = π(6 cm)² = π(36 cm²). Calculating this gives you approximately 113.1 cm². Rounding to the nearest whole number, the area is 113 cm². Now, here's a fun fact: Did you know that the concept of π (pi) has been around for thousands of years? Ancient civilizations like the Babylonians and Egyptians had their own ways of approximating π, but it wasn't until the 18th century that it was defined more rigorously as the ratio of a circle's circumference to its diameter! Next up, if you're tackling circle-related problems, beware of mixing up the formulas! Many students often confuse the area formula with that of the circumference (C = 2πr). Double-check your calculations and make sure you're applying the right formula for the task at hand. It's an easy mix-up that can lead to incorrect answers!
