The volume of the cylinder is equal to the sum of all spheres
the volume of 1 sphere is V1=4/3×pi×(1/2 x)³
simplified V1=1/6×pi×x²
we conclude that the volume of the cylinder is V2=270V1
V2=45×pi×x³
also the V2 can be calculated from the cylinder
V2= base(circle)×height
V2=(3x)²×pi×h=9x²×h
so we have
9x²×pi×h=45×pi×x³
simplified h=5x
Answer:
A) (56)^−2
Step-by-step explanation:
(22 + 34)^−2
Parentheses first
22+34= 56
56 ^-2
B. supplementary
The measures of supplementary angles add up to 180 degrees.
Yeah I don’t know but have someone else
