You graph a rectangle on a coordinate plane that has vertices (0,0), (3,0), (0,2), and (3,2). You then rotate that figure 360 de
wolverine [178]
From the points given we know that the rectangle is 3 points wide and 2 points tall. If we rotate it 360^{\circ} around the x axis then we will receive the lying cyllinder which will be 3 points tall and 2 points wide (so its radius is 2/2 = 1 point). Now we can find the surface area of the cyllinder using appropriate formula:
A=2\pi r^2 + 2\pi rh=2\pi*1^2 + 2 \pi * 1 * 3=2\pi + 6\pi=8\pi\approx 25.13

A coin is tossed 20 times with the following results:
Rudik [331]

Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:

p = 9/20 = 0.45 = 45%.
