Answer:

586.4 in

Step-by-step explanation:

i) V1 = πr²h

= π x 4² x 9

= 452.4

ii) V2 = 2/3 x π x r³

= 2/3 x π x 4³

= 134

iii) V = V1 + V2

V = 452.4 + 134

= 586.4

zhenek [66]

If i understand you are wanting to find the value of g

so if 2/5 of the unkown value g is equal to -14 you would find out that 1/5 g would be -7 so to find g you times -7 by 5 and get -35

g= -35

MatroZZZ [7]

Using a system of equations, it is found that Peter had $48 at first.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable x: Peter's money.

Variable y: Henry's money.

The ratio of peters money to henrys money is 4 : 3, hence:

$\frac{x}{y} = \frac{4}{3}$

After Peter spent $12, they had the same amount, hence:

y = x - 12.

Then, replacing in the ratio:

$\frac{x}{y} = \frac{4}{3}$

$\frac{x}{x - 12} = \frac{4}{3}$

4(x - 12) = 3x

x = 48.
