Answer:
A
Step-by-step explanation:
isolate r by dividing by πh. take the square root on both sides to get rid of the r^2 to make it just r

Answer: Short piece is 27 inches</h3>
Long piece is 81 inches
====================================================
Explanation:
x = length of short piece
3x = length of the longer piece (3 times longer)
x+3x = 4x = total length
total length = 108
So 4x = 108 is the equation which solves to x = 27 after dividing both sides by 4.
The short piece is x = 27 inches and the long piece is 3*x = 3*27 = 81 inches. Adding the two pieces gives 27+81 = 108 which helps confirm the answer.
3(t + 5) = 12
3(t) + 3(5) = 12
3t + 15 = 12
- 15 - 15
3t = -3
3 3
t = -1
-(c - 8) = 0
-(c) - (-8) = 0
-c + 8 = 0
- 8 - 8
-c = -8
-1 -1
c = 8
-10(s + 3) = 9
-10(s) - 10(3) = 9
-10s - 30 = 9
+ 30 + 30
-10s = 39
-10 -10
s = -3.9
2(f - 7) = 2
2(f) - 2(7) = 2
2f - 14 = 2
+ 14 + 14
2f = 16
2 2
f = 8
-7(2t + 5) = -21
-7(2t) - 7(5) = -21
-14t - 35 = -21
+ 35 + 35
-14t = 14
-14 -14
t = -1
1²/₃(3w + 10) = 0
1²/₃(3w) + 1²/₃(10) = 0
5w + 16²/₃ = 0
- 16²/₃ - 16²/₃
5w = -16²/₃

w = -3¹/₃
⁵/₉(°F - 32) = °C
⁵/₉(°F - 32) = 8
⁵/₉(°F) - ⁵/₉(32) = 8
⁵/₉°F - 17⁷/₉ = 8
+ 17⁷/₉ + 17⁷/₉
⁵/₉°F = 25⁷/₉
1⁴/₅(⁵/₉°F) = 1⁴/₅(25⁷/₉)
°F = 46²/₅
