The volume of a cylinder is 180 cubic meters. The height of the cylinder is 11.25 meters. What is the radius of the cylinder?

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

= r²

to maintain accuracy, don't divide yet

now you know what r² is but you want r, so square root it:

=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.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
