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

Question

A. 28.73 m2

B. 57.46 m2

C. 180.52 m2

D. 262.89 m2

Answer 1

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

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

where \( r \) is the radius. In this case, the radius \( r \) is 9.15 m.

Now, plugging in the value of the radius:

\[ \text{Area} = \pi (9.15)^2 \approx 3.14159 \times 83.7225 \approx 262.89 , m^2 \]

Thus, the approximate area of the circle is D. 262.89 m².
