A = X, AC = XZ, and C = Z
L =
w
a = 12
Length times width = area
L · w = a
w · w = 12
= 12
Divide both sides by
or mulitply both sides by
(either one is fine)
÷
= 12 ÷
or
= 12
= 18
Square root both sides to get rid of the squared on the w
=
w = 4.24
Step-by-step explanation:
the volume of a cylinder is
base area × height = pi×r² × height
with r being the radius.
so, we get
pi×6² × 10 = pi×36 + 10 = 360pi =
= 1,130.973355... ft³
now we need to look at the conversion rate between feet and meters :
1 ft = 0.3048 m
1 ft² = 0.3048² m² = 0.09290304 m²
1 f³ = 0.3048³ m³ = 0.028316847... m³
1,130.973355... ft³ = 1,130.973355... × 0.028316847... =
= 32.025599... m³
so, something is not right with your answer options. it looks like you put maybe the answer options of a different question in here.
but none of them get even close to the actual solution of the given question.
Answer:
4578.12 ft³
Step-by-step explanation:
Volume of a cylinder is: V = πr²h
Insert the information into the formula: V = (3.14)(81)(18) = 4578.12
Selection B is appropriate.
_____
The signs of the coefficients tell you the binomial factors must have both signs positive (selections B and C only). Selection B produces an x-term that is 15x+15x=30x (as we want); selection C produces an x-term that is 45x+5x=50x (not what we want).
