Best Answer

The area of a circle with radius

r

is given by the formula

A = π r^{2}

. We are given that the radius of the button on Quinn’s pants is 4 millimeters. We can substitute

r = 4

and

π = 3.14

into the formula to find the area:

A = π r^{2} = 3.14 \cdot 4^{2} = 50.24 sq mm

Therefore, the area of the button is approximately

50.24

square millimeters.
