How would you express the area of a circle approximately if its radius is 4?

To determine the area of a circle, the formula used is ( A = \pi r^2 ), where ( A ) is the area and ( r ) is the radius. In this case, the radius is given as 4.

Calculating the area:

1. First, square the radius: [ 4^2 = 16 ]

2. Next, multiply that result by ( \pi ) (approximately 3.14): [ A \approx \pi \times 16 ] [ A \approx 3.14 \times 16 ] [ A \approx 50.24 ]

This value is very close to 50.27, which would be an appropriate rounding of the area when using ( \pi ) as approximately 3.14159.

Thus, since 50.27 is derived from applying the area formula correctly with the radius of 4, it accurately represents the approximate area of the circle given the information provided.
