B. 282.6 cm
C. 45
D. 10
Answer:
A. 36.4cm = h
Step-by-step explanation:
A=2πrh+2πr² This is the equation to find the surface area of a cylinder
2532 = 2π(9)h + 2π(9)² Multiply
2532 = 18πh + 2π(81) Multiply
2532 = 56.55h + 162π Multiply
2532 = 56.55h + 508.94
-508.94 - 508.94 Subtract 508.94 from both sides
2023.06 = 56.55h Divide both sides by 56.55
36.4cm = h

Answer:
Step-by-step explanation:
Ethan, this is a quadratic equation. We should rewrite this in standard quadratic form: 4x^2 + 16x - 9 = 0. Let's use the quadratic formula approach to solve this:
The coefficients of x are a = 4, b = 16 and c = -9. Thus, the discriminant is
b^2 - 4ac, or 16^2 - 4(4)(-9), or 256 - 144, or 112.
The two solutions are real and are as follows:
-16 ± √112 -16 ± √(16*7) -16 ± 4√7
x = ------------------- = ----------------------- = -----------------
2(4) 8 8
Or, after simplification,
-4 ± √7
x = --------------
