The radius of a circle is 4 m . Find its area to the nearest whole number.

To find the area of a circle, you can use the formula A = πr², where r is the radius. For a circle with a radius of 4 m, the area would be A = π(4 m)² = π(16 m²). If we take π as approximately 3.14, the area comes out to about 50.24 m². Rounded to the nearest whole number, the area is 50 m². Circle area calculations have been around for thousands of years! Ancient civilizations like the Babylonians and Egyptians used early approximations of π to solve practical problems, from building structures to land surveying. So next time you find the area of a circle, you’re echoing the math moves of history’s finest minds!
