Question

What is the best approximation for the area of this circle? Use 3.14 to approximate pi. 25.1 in² 50.2 in² 201.0 in² 803.8 in² Circle with radius labeled 8 in.

Answer 1

The formula for the area on a circle is pi x radius squared.
So by estimating, 8x8 = 64.
64 x 3 is about 200. So the area is estimated to be 201in^2

Answer 2

The best approximation is
`201.0\ in^(2)`

Explanation:

we know that

The area of the circle is equal to

`A=\pi r^(2)`

In this problem we have

`r=8\ in`

`\pi =3.14`

substitute

`A=(3.14)(8^(2))=201.0\ in^(2)`
