Answer :
Answer:
Option C- 314 in²
Step-by-step explanation:
Given : Radius of the circle r=10 inches
To find : What is the area of a circle ?
Solution :
Formula of area of circle
[tex]A=\pi r^2[/tex]
Where A is area , r is radius= 10 and [tex]\pi =3.14[/tex] (given)
Put value in the formula we get,
[tex]A=3.14\times 10^2[/tex]
[tex]A=3.14\times 100[/tex]
[tex]A=314 in^2[/tex]
Therefore, Area of circle is 314 square inches.
So, Option C is correct.

Final answer:
The area of a circle with a radius of 10 inches is calculated using the formula A = πr². Substituting the given radius into the formula with pi approximated as 3.14, the area is found to be 314 inches².
Explanation:
To calculate the area of a circle, we use the formula A = πr², where π (pi) is a constant approximately equal to 3.14 and r represents the radius. Given that the radius of the circle is 10 inches, we substitute the value into the formula:
A = 3.14 × (10 inches)²
Upon squaring the radius and multiplying by pi, we get:
A = 3.14 × 100 inches²
A = 314 inches²
Therefore, the area of the circle is 314 inches².
