the radius of a circle is 9.15 m. what is the approximate area of the circle?

1 answer

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.

Given that the radius \( r \) is 9.15 m, you can substitute this value into the formula:

\[ \text{Area} \approx \pi \times (9.15)^2 \]

First, calculate \( (9.15)^2 \):

\[ (9.15)^2 \approx 83.7225 \]

Now, multiply by \( \pi \) (approximately 3.14159):

\[ \text{Area} \approx 3.14159 \times 83.7225 \approx 262.57 , m^2 \]

Thus, the approximate area of the circle is:

\[ \text{Area} \approx 262.57 , m^2 \]
