ANSWER

d. 314

EXPLANATION

The area of a circle is calculated using the formula:

$Area = \pi {r}^(2)$

It was given in the question that, the circle has radius r=10 units. We substitute this value and π=3.14 into the formula to get,

$Area = 3.14 * {10}^(2)$

$\implies \: Area = 3.14 * 100$

$Area = 314 \: {in}^(2)$

The correct answer is D.

Answer:

d. 314 in²

Explanation:

Area of a circle=πr²where r is the radius of the circle.

A=πr²

=π×10²

=314.2 in²

Area of the circle is 314 in² to the nearest square inch.
