Question

What is the area of a circle with a radius of 2.1cm? Use 3.14 for π.

Answer 1

Answer:

A= 13.8474

Step-by-step explanation:

The formula for the area of a circle is A= πr^2 (pi times r, or radius, squared).

So if you insert the values into the formula you have....

A= 3.14(2.1 cm)^2

You can use a calculator from there to get....

A= 13.8474
