Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2

Answer:
2.48 cubic inches
Step-by-step explanation:
This is very simple. We need to find the volume of a sphere.
THe formula of volume of a sphere is given by:
![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
Where
V is the volume, and r is the radius
We know radius is HALF of diameter, so r = 1.68/2 = 0.84
<em>Now, we plug in the info given into the formula and figure out the answer:</em>
<em>
</em>
<em>The answer is: the volume is 2.48 cubic inches</em>
