Answer:
2 miles
Step-by-step explanation:
<u>Answer </u>
7
<u>Explanation. </u>
The triangle shown is a right triangle. One of the acute angles is given as 45°. Angles in a triangle add up to 180°
So we can get the third angle of the triangle as follows:
180 - (90+45) = 45.
From this we can conclude that, apart from the triangle being an right triangle, it is also isosceles triangle. This means that the two shorter sides of the triangle are equal.
So, the value of x is 7.
Since the volume is πr^2h, we plug it in to get π(12.2)^2*12.2=1815.848*π= about 5704.66

-66d-21 Answer
Using it's concept, it is found that there is a 0.125 = 12.5% experimental probability that a randomly selected preschooler would choose to read books today.
<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 numbers of outcomes are taken from previous trials.
In this problem, in the previous trial, one out of eight students read a book, hence:
p = 1/8 = 0.125 = 12.5%.
There is a 0.125 = 12.5% experimental probability that a randomly selected preschooler would choose to read books today.
