Answer 1

The area of a circle is given by the formula A = πr^2, where r is the radius of the circle.

Given that the radius of the circle is 4 cm, we can substitute that into the formula:

A = π(4)^2
A = 16π

Approximating π to 3.14, we get:

A ≈ 16 * 3.14
A ≈ 50.24 cm^2

So, the area of the circle is approximately 50.24 cm^2.

Therefore, the correct answer is: 50.24 cm2.
