Which expression represents the approximate area of the circle in square inches?
can i pls get help :(

Answer 1

A circle is a curve sketched out by a point moving in a plane. The area of the circle will be equal to 28.26 in².

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The area of the circle will be approximately equal to the area of the parallelogram. Therefore, the area of the parallelogram can be written as,

$\text{Area of parallelogram} = 9.42 \times 3 = 28.26\rm\ in^2$

Hence, the area of the circle will be equal to 28.26 in².
