Answer:
185.60944
Step-by-step explanation:
Using the formulas
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·4·(4+102+42)≈185.60944
Answer:
x = 5
Step-by-step explanation:
x² + (2x+2)² = (2x+3)²
x² + 4x² + 8x + 4 = 4x² + 12x + 9
x² - 4x - 5 = 0
(x - 5)(x + 1) = 0
x = -1 This can be discounted as the answer because you cannot have a negative length
answer: x = 5
