What is the area of a circle with a radius of 4 cm? (Use π = 3.14)

To find the area of a circle, you can use the formula:

[ \text{Area} = \pi r^2 ]

where ( r ) is the radius of the circle.

In this question, the radius ( r ) is 4 cm. Plugging this value into the formula gives:

[ \text{Area} = \pi \times (4 , \text{cm})^2 ]

[ = \pi \times 16 , \text{cm}^2 ]

Now, substituting ( \pi ) with 3.14, you have:

[ \text{Area} = 3.14 \times 16 , \text{cm}^2 ]

Calculating that:

[ 3.14 \times 16 = 50.24 , \text{cm}^2 ]

Thus, the area of the circle with a radius of 4 cm is 50.24 cm². This aligns with the choice that reflects the correct application of the area formula and the correct multiplication of values.
