Question

Find the area of a circle that has a diameter = 18

Answer 1

Answer:

About 254.469 square units

Step-by-step explanation:

To find the area of a circle, you need to multiply the square of the radius by pi. To find the radius of a circle, you need to divide the diameter by 2, which in this case is 18/2=9. Now, you can plug it into the formula to find that the area of this circle is $\pi \cdot 9^2 \approx 254.469$. Hope this helps!
