Answer:
l = 2.25 cm
Step-by-step explanation:
given l is inversely proportional to w² then the equation relating them is
l = 
← k is the constant of proportion
(i)
to find k use the condition w = 1.5 , l = 16 , then
16 = 
= 
( multiply both sides by 2.25 )
36 = k
l = 
← equation of proportion
(ii)
when w = 4 , then
l = 
= 
= 2.25 cm
To solve this question, use the Cube surface area formula
Area = 6a^2 in which a = edge.
edge = 8.5
Area = 6(8.5)²
Simplify. Follow PEMDAS
Area = 6(72.25)
Area = 433.5
(C) 433.5 in² is your answer
hope this helps
You can use the slope intercept form for the line equation
Answer:
V ≈ 2144.70 
Step-by-step explanation:
Radius is going to be used instead of the diameter. Half of 16 is 8, and so that will be the value that shall be used.
V ≈ 2144.66
V ≈ 2144.70
Is it not zero ???? ? ? ?
