Question
For Christmas, Lily makes a paper cone Santa hat. If the height and radius of the cone are 8 inches and 3 inches respectively, what is the volume of the hat? (use π = 3.14)
- 75.35 cubic inches
- 75.33 cubic inches
- 75.34 cubic inches
- 75.36 cubic inches
Hint:
Volume of a cone = (1/3)πr2h
The correct answer is: 75.36 cubic inches
We have given the dimensions of a paper cone Santa hat made by Lily
Radius, r = 3 in
Height, h = 8 in
We have to find the volume of the given hat
We know that
Volume of a cone = (1/3)πr2h
= (1/3)(3.14)(3 x 3)(8)
= (3.14)(3 x 8)
= (3.14)(24)
= 75.36 in3
The volume of conical hat = 75.36 in3
Therefore correct option is d) 75.36 in3
The volume of conical hat = 75.36 in3
Therefore correct option is d) 75.36 in3
