Answer:

The area of the resulting cross section is 78.5\ m^{2}

Step-by-step explanation:

we know that

The resulting cross section is a circle congruent with the circle of the base of cylinder

therefore

The area is equal to

A=\pi r^{2}

we have

\pi=3.14

r=10/2=5\ m -----> the radius is half the diameter

substitute the values

A=(3.14)(5)^{2}=78.5\ m^{2}

OleMash [197]

Answer: 15 feet

Step-by-step explanation:

From the question, we are informed that a diving board is 10 feet above a pool. Since the ladder is 5 feet away from the base of the diving board, to calculate how tall is the ladder is, we subtract -5 from 10. This will be:

= 10 - (-5)

= 10 + 5

= 15 feet

The answer is option C.

When the movie is half over, popcorn sells for half price. Full price popcorn is $3.50, and drinks are $1.35. Determine the cost
Nady [450]
Full price of popcorn: $3.50 
Price of popcorn after half the movie: $1.75
price of drinks: $1.35 

The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over." 

$1.75*3=$5.25
$1.35*3=$4.05

the price of the 3 orders of popcorn would be $5.25 
The price of the 3 orders of drink would be $4.05 

5.25 + 4.05 = $9.30 

In total the 3 orders of popcorn and 3 orders of drink would cost $9.30

Hope this helps! :)
