A swimming pool has a diameter of 32 feet. What is the area of the swimming pool that needs to be covered by a tarp?
1 answer:
To get the area of a circle, use this formula: A = 
* radius^2
We can use 3.14 for.
And because this formula uses the radius and not the diameter, we will need to convert the diameter into a radius. The radius is half of a diameter.
32 / 2 = 16
Now we have our radius.
A = 3.14 * 16^2
A = 3.14 * 256
A = <span>803.84
So, you will need to have a tarp that is at least 803.84 feet squared to cover the pool.</span>

As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.
In order to solve for x we can set up the proportion between the horizontal and vertical sides:
Solving this proportion for x implies
Now you can solve for m and p using the pythagorean theorem, because both triangles are right:
Then, we know that the hypothenuse of the big triangle is m+p, so we have
which implies
