Answer:
254.34 ft²
Step-by-step explanation:
Formula for the area of a circle: [tex]A=\pi r^{2}[/tex]
To solve this problem, all you need to do is plug in the correct values for the variables and solve.
1) In the formula, r stands for radius of the circle, which is half of the diameter. Knowing this, we can find the radius by dividing 18 by 2 to get 9. So, r = 9.
2) The problem also tells us to use 3.14 for pi, so that's a given.
3) With all of this information, we can plug in the appropriate values for each variable to get. [tex]A=3.14(9^{2})[/tex] Now, solve the problem and you should have get [tex]A=254.34[/tex].
