A cylinder has a volume of 375 cubic centimeters. The radius of the cylinder is 12.5 centimeters. What is the approximate height of the cylinder? Use 3.14 for π π. A. 9.6 centimeters B. 7.5 centimeters C. 2.4 centimeters D. 0.8 centimeter

Question

I think its C but im not sure please help

Answer 1

V = π r^2 h
375 = π(12.5)^2 h
h = 375/(12.5^2 π) = ...

Not b)
watch your order of operation, I made sure to put brackets around the whole denominator

Answer 2

so Is it A?

Answer 3

No, are you just guessing
show me your "in-between steps" calculations.

Answer 4

Well My dad tried helping me and he said to do pi times the 375 then divide the 12.5 but i think that was wrong so i said A because when I asked my mom she guessed A

Answer 5

geeeshh, all that guessing.

h = 375/(12.5^2 π)
= 375/(156.25π)
= 375/490.8738....
= .7639...

or d) rounded to .8

Answer 6

ohhh ok thank you so much! very apperciated :) Now im one step closer to passing 8th grade

Answer 7
