It has 2 real solutions which are 5 and 8

notice, if the original area was πr², then the new area has a factor in front of it, that much.
Answer:
The formula for calculating the circumference of a circle is 2*pi*r. Because pi does not have an end, we'll use 3.14, since that is the approximate value of pi.
2*6*3.14 = 37.68
The outer rim of the pool is about 37.68 meters long
Step-by-step explanation:
It’s probably 40 because it says about how long not exactly.
I hope this helped
Answer:
a(85) = -1033
Step-by-step explanation:
Explicit Arithmetic Sequence:
an = a1 + d(n-1)
d = -12 (by -37 + 25)
a(85) = -25 + -12(85-1)
a(85) = -1033
