<u>Answer:</u>

The correct answer option is C. 56.

<u>Step-by-step explanation:</u>

We are given that a group of 8 friends (5 girls and 3 boys) plans to watch a movie, but they have only 5 tickets.

We are to find the number of combinations these 5 friends could

possibly receive the tickets.

Here, we will use the concept of combination as the order of the friends is not specific.

$5C5+ (5C4 * 3C1) + (5C3*3C2) + (5C2*3C3)$

$=1+5*3 + 10*3 +10*1 = 1+15+30+10=$ 56

A cylinder has a base with a radius of 5 cm and a height of 15 cm. What is the volume of the cylinder? (Use π = 3.14.) A. 471 cm

eduard

The formula for volume is
$V=\pi r^{2}h$
We plug in:
$V=\pi (5)^{2}(15)$
$=\pi (25)(15)$
$=375\pi$
$=375*3.14=1177.5$
