Answer 1

Explanation:

The formula to find the perimeter or circumference of a circle is P=2×π×r.

Step 1: Find the radius. In this case it is 10 in.

Step 2: Multiply the radius by 2 for simplicity. In this case 10×2=20.

Step 3: Multiply the last number by π. In this case, 20×3.14=62.8.

Step 4: You have the answer. Hope this helps!

Answer 2

The circumference is 62.83in
