Given
The attached triangle
Required
Find h, x and y
Let the base of the triangle be 15.
So, the area is:




Let the base of the triangle be 25.
So, the area is:



Substitute 

Solve for h



Considering the smallest triangle

So:


This gives:


Take square roots


Solving for y




Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.

Here, we are given that our sphere has a radius of 4 units.
So plugging into the formula, we have
.
Start by simplifying the exponent.
(4 units)³ is equal to (4 units) (4 units) (4 units) or 64 units³.
So we have
.
Next, we multiply (4/3)(64) which can
be thought of as (4/3)(64/1)
So multiplying across the numerators and across the denominators,
we have
.
