only one time in same size of conical glass
and the same quanlity to each AB= 6cm es
the diameter chase of the soft drink cone
in the whical glass and depth of this
one is 5cm find the quantity of the soft
drink in litres which is just cufficient for
40 guesti (Take T= 3.145​

Answer 1

Volumeofcone=1/3?3.14or22/7? r sq ?h Diameter=6cm So, Radius=6/2=3cm Height=5cm So; Volume = 1/2?3.14?3?5 Which is=3.14?5=15.70 . Since you require the Answer in Litres You divide 15.7/1000=0.01570 . Therefore the drink required for 40 guests = 40?0.1570=0.628Litres.

Hope that helps

Answer 2

Answer:

Given, the diameter of the cone = 6 cm

So, its radius r = 6/2 = 3 cm

Depth/height (h) of the cone = 5 cm

Now, volume of the cone = (1/3) * π * r2 * h

= (1/3) * 3.14 * 32 * 5

= 3.14 * 3 * 5

= 47.1 cm3

= 47.1/1000 litre [Since 1000 cm3 = 1 litre]

= 0.0471 litres

Now, the quantity of soft drinks for 40 guests = 40 * 0.0471

= 1.884 litres
