Question

4 in
Shape: Circle
Calculate the area of the circle.
Area of a circle: 3.14 x r²
A = [?] in²
Round to the nearest hundredth.

Answer 1

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

\[
A = \pi r^2
\]

In your case, the radius \( r \) is 4 inches. We can use \( \pi \approx 3.14 \) for the calculations.

\[
A = 3.14 \times (4)^2
\]

First, calculate \( (4)^2 \):

\[
(4)^2 = 16
\]

Now, plug this value back into the area formula:

\[
A = 3.14 \times 16
\]

Now, perform the multiplication:

\[
A = 50.24
\]

So, the area of the circle is:

\[
A \approx 50.24 \text{ in}^2
\]

Rounded to the nearest hundredth, the area is \( 50.24 \text{ in}^2 \).
