Question

Find the area of the circle.

Round to the nearest hundredth.

Answer 1

area = pi * r^2  = pi * 3^2 = 9pi

that is 28.27 to nearest 1/100.

Answer 2

To find the area of any circle, use the equation pi*r^2. You have the radius, which is 3, so substitute 3 into the equation. Pi*3^2. 3^2 is equal to 9, so now multiply 9 by 3.14, pi. After multiplying you will get 28.27, your answer rounded to the nearest hundredth.
