Question

Al fills an ice cream cone to the top edge. The diameter of the ice cream cone is 2 inches and its height is 6 inches. Don fills a bowl (V = 5 cubic inches) with ice cream. Al has how much more ice cream than Don? A) 1.2in3 B) 1.28in3 C) 1.1in3 D) 1in3

Answer 1

Answer:

B) 1.28 in3

Step-by-step explanation:

Given : Diameter = 2 inches i.e.

Radius = 1 inches

Height = 6 inches

Firstly we find volume of cone ,

Volume of cone = 1/3 π r^2 h

= 1/3* 3.14 * 1* 1 * 6

= 1/3 * 18.84

= 6.28 in^ 3

It is given that the cone is full with ice cream

therefore, volume of cone = volume of ice cream

i.e. volume of ice cream fills by Al in cone = 6.28 cubic inches. ...................(i)

and ice cream fills by Don in bowl = 5 cubic inches.......(ii)

On subtracting (ii) by (i) we get ,

1.28 cubic inche

therefore, Al has 1.28cubic inches more ice cream than Don
