Hello There!
Priya has a piece of string which is 5/6 yard long. She cuts 3/5 of string for a project. What is the length of the string she has
left?
Left is a key word for subtract.
The equation is 5/6 - 3/5 = ?
The LCD ( Least Common Denominator ) is 30
5 x 5 3 x 6
--------------- - -------------
6 x 5 5 x 6
25 18 7
-------- - -------- = -------
30 30 30
[ The denominator stays the same]
So, 5/6 - 3/5 =
7/30
Hope this helped!

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).
