I need help find the volume of the composite solid use 3.14 for pi

Evgen [1.6K]

Answer:

$222.312\:\mathrm{in^3}$

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: $\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912$

Volume of the cylinder: $2^2\cdot 3.14 \cdot 15=188.4$

Thus, the total volume of the solid is:

$33.912+188.4=\boxed{222.312\:\mathrm{in^3}}$

Sedaia [141]

Answer:

$\boxed{it \: is \: (\frac{(k - 12)}{8} )\times 10^2 \: \: times \: more}$

Step-by-step explanation:

$............................................................... \\ to \: find \: this\: ans :we \: find \: the \: ratio \\ of \: the \: overall \: number \: of \: students \: to \: \\ the \: aveerage \: number \:o f \:students \\ ............................................................... \\ans \: = \frac{overall \: number \: of \: students}{aveerage \: number \:o f \:students} = \frac{k - 12}{8 \times 10^2} \\ therefore \: it \: is \: (\frac{(k - 12)}{8} )\times 10^2 \: \: times \: more.$
