Question

A right cylinder has the radius of 3.5cm and the height of 11cm if i place 3 ice cube with edge length of 2cm in the glass what volume of juice will i add to fill the glass to the top?

Answer 1

Answer:

Volume of cylinder =

$\pi \times r {}^{2} \times h$

$\pi \times 3.5 {}^{2} \times 11 = 423cm {}^{3}$

Volume of 1 ice cube = 2*2*2= 8cm3

Volume of 3 ice cubes= 3*8= 24cm3

Volume of juice added = 423-24 = 399 cm3
