Question

The area of a circle is approximately 3.14 times the radius squared. Which of the following is the correct way to write the expression that represents the area, if the radius is x?A) x(3.14)^2B) 3.14x^2C) (3.14x)^2D) 2(3.14)x

Answer 1

The given information tells us that the area of a circle is approx 3.14 times the radius square:

Radius square = x^2

The word times could be used as another word for multiply:

Therefore:

3.12(x^2) is the approx area of a circle.

The correct answer is option B.
