<h3>Given:</h3>

Radius of 50 point region= 3 in
Width of other regions= 4 in

<h3>To find:</h3>

The area of the target which earns 30 points on a throw.

<h3>Solution:</h3>

$\huge\boxed{Formula: a= \pi{r}^{2}}$

$4+3$

$=7$

Let's solve

We have to find the answer in terms of π so, we'll just have to multiply the radius by itself.

$a={7}^{2}$

$\large\boxed{a= 49 \pi\: {in}^{2}}$

<u>Hence,</u><u> </u><u>the</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the target which earns 30 points on a throw</u><u> </u><u>is</u><u> </u><u>4</u><u>9</u><u>π</u><u> </u><u>square</u><u> </u><u>inches</u><u>.</u>

<u>Answer</u><u>=</u><u> </u><u>Option</u><u> </u><u>B</u>
