Answer:
arc = 26 units
Step-by-step explanation:
130 = 360°
(72° arc/360°)(72) = 26
Answer:
Option C. 
Step-by-step explanation:
<u><em>The correct inequality is</em></u>
Solve for x
subtract 14 both sides


Multiply by -1 both sides

Multiply by 5/2 both sides


Answer:
f(x) = 2π (11 + sin x) √(1 + cos²x)
Step-by-step explanation:
Surface area of a curve rotated about y = a is:
S = ∫ 2π (y − a) ds,
where ds = √(1 + (dy/dx)²) dx.
y = 6 + sin x, and a = -5. dy/dx = cos x. Plugging in:
S = ∫₀²ᵖⁱ 2π (6 + sin x − -5) √(1 + cos²x) dx
S = ∫₀²ᵖⁱ 2π (11 + sin x) √(1 + cos²x) dx
Therefore, f(x) = 2π (11 + sin x) √(1 + cos²x).
Answer:
343 - 64 + 457 Solve then you get your answer
Answer:
60
Step-by-step explanation:
if its 20 rotation it goes 3 times it will be 60
20 20 20= <u>60</u>
