Question

A window has a radius of 12 inches. What is the circumference of the window? Use 3.14 to approximate pi. Round your answer to the nearest whole number.

Answer 1

You can use π*R² to work out the area of a circle,
The radius has been given to you so...
π*12² = 452.38

The area is 452.38 inches²

You can use π*2r to work out the circumference;
π*24 = 75.3 inches
Hope this helps! :)

Answer 2

75 inch is the circumference
