Step-by-step explanation:
-2u = 2i + 10j
V = 4i - 6j
(-2u).V = (2x4) - (10x-6)
= 8 - (-60)
= 68
Answer:
h = 9
Step-by-step explanation:
cylinder A = *4 = 113.0973355
Cylinder B = 113.0973355
113.0973355 =
*h
113.0973355 / 4
= h
8.999999999998 = h
I think b/c of the rounding error of rounding off pi, that h= 9
