A movie theater has n rows and m seats in each row. If each ticket costs $5.60, how much do all tickets to one movie cost?

docker41 [41]

Answer:

All Tickets to one movie cost $\$5.60 \times m\times n$

Step-by-step explanation:

Given:

Number of rows in theater = n

Number of seats in each row = m

Total number of seats in the theater = Number of rows in theater $\times$ Number of seats in each row= $m \times n$

Now given each ticket costs = $\$5.60$

So to find total of all tickets we need multiply each ticket cost by Total number of seats in the theater

Total tickets cost = each ticket cost $\times$ Total number of seats in the theater = $\$5.60 \times m \times n$

$V=\dfrac{4}{3}\pi r^3\ \ \ |\cdot\dfrac{3}{4}\\\\\pi r^3=\dfrac{3V}{4}\ \ \ \ |:\pi\\\\r^3=\dfrac{3V}{4\pi}\ \ \ |:r\\\\r^2=\dfrac{3V}{4\pi r^2}$

Substitute to S.A.

$S.A.=4\pi r^2=4\pi\cdot\dfrac{3V}{4\pi r^2}=\dfrac{3V}{r}$

$\dfrac{S.A.}{V}=\dfrac{4\pi r^2}{\frac{4}{3}\pi r^3}=\dfrac{3}{r}$

$\dfrac{S.A.}{V}=1\to\dfrac{3}{r}=1\to r=3$
