In order to solve this problem, you must first make sure both fractions have the same denominator. In this instance, you have both a fraction and a whole number.
This actually makes it easier, since 15 can also be 14 8/8 which satisfies the need for the same denominator.
New expression:
14 8/8 - 7 5/8
Subtract the whole numbers
14 - 7 = 7
subtract the numerators
8 - 5 = 3
Answer is 7 3/8

The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in
the answer is
8 in
2.89 rounded is 3 2.82 rounded is 2.80 which = 2.8 you minus 3-2.8 it = 0.2
One way of solving this problem can be Heron's formula. It is a formula that allows us to compute the area of a triangle, knowing the length of its three sides.
For the sake of clarity, let's assume that the point in the top-left lies in the origin, and let's call it point A. Then, the "middle" point is point B, and the bottom-right point is point C.
If we fix the coordinate axis with the origin in A, we have the following coordinates for the three points:

We can compute the length of any side using the formula for the distance between two points:

Plugging the approriate values, we get the following lenghts:

Now that we have the lengths, we can use Heron's formula: given the side lenghts
and the semiperimeter
, the area is given by

If you plug our values, you will get an area of 6.5. So, unless I'm mistaken, none of the answers seem to mach, whereas 7 seems the best approximation.
