A composite figure is formed from a cone and a cylinder with the same base radius, and its volume can be calculated by multiplyi
olga55 [171]

The composite figure comprises of a cone balanced on top of  cylinder

Step-by-step explanation:

The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r

Then the volume of the cone will be V_{cone}

Then the volume of the cylinder will be V_{cylinder}

V_{cylinder}  = \pi r^{2} h_{cylinder}

The total volume of the composite figure will be V, where

V= V_{cone} + V_{cylinder}

V  = \frac{1}{3} \pi r^{2} h_{cone} +\pi r^{2} h_{cylinder}

let the height of cone and cylinder be same

The volume of the composite figure will be \frac{4}{3} \pi rr^{2} h

Hence \frac{4}{3} = \frac{a}{b}

Thecomposite figure comprises of a cone balanced on top of  cylinder

A function will not have repeating x values...all the x values will be different. But u don't want a function...so u want repeating x values.
That leaves C...because u have repeating x values (3 is ur repeating x value)...so C is not a function
