Answer :
Answer: 314 square inches
Work Shown:
A = pi*r^2
A = 3.14 * 10^2
A = 3.14 * 100
A = 314 square inches
This value is approximate since pi = 3.14 is approximate.

The area of the circle is :
↬ 314 in²
Work:
To calculate the circle's area, I will use the formula
[tex]\sf{C=\pi r^2}[/tex]
where
- C = circumference
- π = 3.14
- r = radius (10 inches)

Plug in the values :
[tex]\begin{gathered}\sf{A=3.14\times10^2}\\\\\sf{A=3.14\times100}\\\\\boxed{\boxed{\bf{A=314\:in^2}}}\end{gathered}[/tex]
