If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π
Fill in the exact length for "s" in the formula and compute to find the radius.

Answer:
(x-9) (x-3)
Step-by-step explanation:
x^2 -12x +27
What 2 numbers multiply to 27 and add to -12
-9* -3 = 27
-9-3 = -12
(x-9) (x-3)
The one on the right is 22.

which gives u a price of 22 per gallon
Answer:
1.25.
Step-by-step explanation:
The common ratio r is 1/5 and the first term a1 = (1/5)^(1-1) = 1.
Sum to infinity = a1 / (1 - r)
= 1 / (1 - 1/5)
= 1 / 4/5
= 5/4
= 1.25 (answer)
