The volume of the cylinder is given by:
V = pi * r ^ 2 * h
For h = 12cm:
V1 = pi * ((21) ^ 2) * (12)
V1 = 16625.30832 cm ^ 3
For h = 11.9cm:
V2 = pi * ((21) ^ 2) * (11.9)
V2 = 16486.76409 cm ^ 3
The change in volume is given by:
V1-V2 = 16625.30832-16486.76409
V1-V2 = 138.54423 cm ^ 3
Answer:
the change in the volume is:
V1-V2 = 138.54423 cm ^ 3
Answer:
the answer is 15:75
Step-by-step explanation:
(1+5)=6
£90/6=15
So, (1×15):(5×15)
=15:75
Answer:
Hello!!!
In this specific case the constant of proportionality is s (speed).
Step-by-step explanation:
The constant of proportionality stay "constant" (as the name suggests) in a certain case.
meaning, the speed itself remains constant at any given distance or time.
You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.
you can also switch up the formula:
d=st
t=d/s
s=d/t
i really hope this helps!!!!!
