Answer:
43.43/43
Step-by-step explanation:
The 3rd option, x=75y=35.
The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)

an = a1 + d(n - 1)
a20 = -6 + 2(20-1) = 32
