Tin with oil

Tin with oil has the shape of a rotating cylinder whose height is equal to the diameter of its base. Canned surface is 1884 cm2. Calculate how many liters of oil is in the tin.

Correct result:

V =  6.2784 l

Solution:

S=1884 cm2=18.84 dm2 S=2πr2+2πr(2r)=6πr2 r=S/6/π=1 dm h=2r=2 dm  1 dm3=1 l V=πr2h=6.2784 l



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
