Question

1. What is the radius of the top of the cup? Explain your reasoning.

2. What is the volume of the water in the cup?

(See image)

Answer 1

the volume is 1071.787cm cube
so, volume of cone = pi x r x r x h / 3
                               = 3.14 x 8 x 8 x 16 / 3
                                 =3215.36 / 3
                                       =1071.8cm cube
