Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>

<span>The new ratio is obtained like this:
</span>

.
From the above equation we get

.
then

Solving the above equation for y we get:

So
So the first tree is (400-160=240) more taller than cherry tree.

Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

or

We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
Add 10 to both sides. X is 2. A.
