The area if the of a circle is 111.6 square centimeters. What is the diameter?

2 answers:

7 0

The equation for a circle's area is \pi r^2. and the equation for the diameter is 2\pi r . lets find r. we have 111.6=3.14*r^2. divide by 3.14 on both sides. that makes 36=r^2 take the square root of both sides. r=6.
now we find the diameter. 2\pi r=2*3.14*6=3.14*12 which is approximately 38.68

A continuous random variable can take any value within an interval.
Thus, it can take infinite values since there are infinite numbers in an interval.
A continuous variable is a variable whose value is obtained by measuring.
Examples: height of students in class , weight of students in class, time it takes to get to school, distance traveled between classes.
Thus, the correct meaning of continuous random variable is explained by Option A)

Use the variable x to write the phrase in symbols.

Rudik [331]

Answer:

155 + $x^{3}$ + 14

Step-by-step explanation:

The variable x would represent the number/value we don't know, and in this case, we don't know what number is raised to the third power. This being said, x would represent that number.

The question, although worded a bit confusingly, asks to add 155, the number (x) to the exponent of 3, and 14. Mathematically, this would be 155 + $x^{3}$ + 14.
