Answer:
2.26 meters
Step-by-step explanation:
so the volume for a cylinder is
v= π r² x h
now just substitute in the numbers you know:
180= π r² x 11.25
now rearrange the formula:
180= r² x 11.25π
(rearranging allows you to do this next bit with ease)
now divide by 11.25π on both sides to get
[tex]\frac{180}{11.25\pi }[/tex]= r²
to maintain accuracy, don't divide yet
now you know what r² is but you want r, so square root it:
[tex]\sqrt{\frac{180}{11.25\pi } }[/tex]=r
type that into a calculator and i think the answer is ...
2.25675833419
write the long answer in case you make a mistake when rounding
round appropriately : 2.26 meters ( I've done it to 2 decimal places)
and hopefully that's the correct answer.
