Answer:
Explanation:
16 is especially important, so start with it.
F = 5/9 * C + 32 Subtract 32 from both sides.
F - 32 = 5/9 C + 32 - 32 Combine
F - 32 = 5/9 C Multiply both sides by 9/5
9/5(F - 32) = 9/5 * 5/9 C Combine
9/5(F - 32) = C
Fifteen
V = pi * r^2 * h / 3 Multiply both sides by 3
3V = 3*pi * r^2 * h/ 3 Combine
3V = pi * r^2 * h Divide by pi
3V/(pi ) = r^2 * h Divide by r^2
3V / (pi * r^2) = r^2 * h / r^2 Combine
3V / (pi * r^2) = h
