Question
Mike has a large plastic cup that he is going to fill with water. The plastic cup is in the shape of a cone as shown. Which is closest to the volume of Mike’s cup?
- 21 cubic inches
- 63 cubic inches
- 66 cubic inches
- 198 cubic inches
Hint:
Volume of a cone = (
)πr2h
The correct answer is: 66 cubic inches
We have given the dimensions of a large plastic cup of Mike in shape of cone
Radius, r = 3 in
Height, h = 7 in
We have to find the volume of the given cone
We know that
Volume of a cup = ()πr2h
= ()(3.14)(3 x 3)(7)
= ()(3.14) (9 x 7)
= ()(3.14)(63)
= 197.
= 65.94 in3
= 66 in3
Therefore, the volume of Mike’s cup is 66 in3
Therefore correct option is c) 66 in3.
)(3.14)(3 x 3)(7))(3.14) (9 x 7))(3.14)(63)Therefore, the volume of Mike’s cup is 66 in3
Therefore correct option is c) 66 in3.
