Question

A circle has a diameter of 12 inches. What is the best approximation of its area? Use 3.14 to approximate for π . 18.84 in² 39.14 in² 113.04 in² 452.16 in² HURY PLEASE

Answer 1

A=πr²
12/2=6
6*3.14=18.84
18.84*6=113.04

Answer 2

`113.04\ in^(2)`

Explanation:

we know that

The area of a circle is equal to

`A=\pi r^(2)`

in this problem we have

`r=12/2=6\ in` -----> the radius is half the diameter

substitute

`A=(3.14)(6^(2))=113.04\ in^(2)`
