What is the area of a circle with a radius of 10 inches? use 3.14 for pi.

31.4 in²

62.8 in²

314 in²

628 in²

Area of circle =  314 in².

Step-by-step explanation:

Given : circle with a radius of 10 inches, Use 3.14 for pi.

To find : What is the area of a circle.

Solution : We have given a circle with radius = 10 inches.

Area of circle = pi * ( radius )² .

Plugging values of pi = 3.14 and radius = 10.

Area of circle = 3. 14 * ( 10 )² .

Area of circle = 3.14 * 100.

Area of circle =  314 in².

Therefore, Area of circle =  314 in².

answer: 177/8

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
