A circular swimming pool has a diameter of the 26 feet. What is the area of the swimming pool? Use 3.14 to approximate for π . E
nter your answer, as a decimal rounded to the nearest tenth, in the box.
1 answer:
So the equation for the area of a circle is
![A=3.14(r^2)](https://tex.z-dn.net/?f=A%3D3.14%28r%5E2%29)
First to find the radius, you would need to divide the diameter, 26, by half, which in this case its 13.
Replace the r variable with 13 and solve:
![A=3.14(13^2)](https://tex.z-dn.net/?f=A%3D3.14%2813%5E2%29)
![A=3.14(169)](https://tex.z-dn.net/?f=A%3D3.14%28169%29)
