Area of a circle: 3.14 x r²
A = [?]in²
Round to the nearest hundredth.

1 answer

To calculate the area of the circle with a radius of 2 inches, you can use the formula for the area of a circle:

\[ A = \pi r^2 \]

Given \( \pi \approx 3.14 \) and \( r = 2 \) inches, you plug the values into the formula:

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

Calculating \( (2)^2 \):

\[ (2)^2 = 4 \]

Now substitute that back into the formula:

\[ A = 3.14 \times 4 \]

Now calculate:

\[ A = 12.56 \]

Therefore, the area of the circle is:

\[ A \approx 12.56 , \text{in}^2 \]

When rounding to the nearest hundredth, the area remains:

\[ \boxed{12.56 , \text{in}^2} \]
