Area of a circle = PI*radius^2
10 inch diameter = 5 inch radius
Area = PI* 5^2
Area = <span> <span> <span> 78.5398163397 </span> </span> </span>

<h2>Answer:</h2>

<u>The correct answer is </u><u>B) 78.5</u>

<u></u>

<h2>Step-by-step explanation:</h2>

As we know that

Area of a circle = π (r) ²

Radius will be 1/2d

Radius is 5 inches

So putting the values

Area = 3.14* 25

Area = 78.5398163397
