Answer:
The formula that can be used to solve for h is;
h = S.A/(2πr) - r
Step-by-step explanation:
Here, we want to find the formula that can be used to get the height of the cylinder given the surface area of the cylinder.
Mathematically;
S.A = (2 π r^2 + 2 π r h)
Let’s factor out 2 π r
S.A = 2 π r( r + h)
divide both sides by 2 π r
S.A/2 π r = r + h
h = S.A/(2 π r) - r
This is a great place to apply the Pyth. Theorem. Let the width be W.
Then W^2 + 28^2 = 35^2.
Solving this, we get W^2 = 441. Taking the positive square root, we get
W = 21 ft

Answer:
The man in the goose cross the river, with the fox and the beans together, he leaves the goose on the other side and goes back across.
The man then takes the fox across the river, and since he can’t leave the fox in the goose together, he brings that goose back.
Again, since the goose and the beans can’t be left together, he leaves the goose and he takes the beans across and leaves with the fox.
He returns to pick up the goose and heads back across the river one last time.
