Use 3.14 for pi to calculate the area of a circle of radius 3m

The formula for the area of a circle is A = πr^2.

Plugging in the values given, we get:

A = 3.14 x 3^2
A = 3.14 x 9
A = 28.26

Therefore, the area of a circle of radius 3m is 28.26 square meters.

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

Area = π * (radius)^2

Given that the radius is 3m and using π = 3.14, we can substitute these values into the formula:

Area = 3.14 * (3)^2 = 3.14 * 9 = 28.26 square meters

Therefore, the area of a circle with a radius of 3m is approximately 28.26 square meters.
