The paint can holds 2.5 liters
(1 liter=1000cm)
height=17
work out the radius of the can
(round the correct answer to 1 decimal place)
The small cylinder can fill the big cylinder to a height of 5 cm
work out the radius of the big cylinder
small cylinder radius=6cm
small cylinder height=12 cm
did u just answer ur own question
if so.. nice job!
2.5 L = 2500 cm^3
So
2500 = pi * r^2 * height
2500 = 17 pi * r^2
r^2 = [ 2500 / (17/pi ]
r = sqrt [ 2500 / (17 pi ) ] ≈ 6.84 cm
