Answer:
P = 40 units
Step-by-step explanation:
P = s + s +s + s
P = 8 + 8 + 12 + 12

LKM≈TEJ since it makes the triangles congruent, although the angles in each triangle are not corresponding equal angles
Volume of a sphere is given by the formula:

If we pull the 4 out front we have,

.
Volume of a cone is given by the formula:

Notice that if the height of the cone is equal to the radius,

then it's exactly what we see in our volume formula without the 4!
3.5h+10=5.25h-11
21=1.75h
12=h
3.5(12)+10=5.25(12)-11
52=52
