Circumference is equal to diameter multiplied by pi. C=d X pi. To find the radius we need to rearrange this equation. We know what pi and the circumference are, so to find diameter we do circumference divided by pi. D=c/pi. 942/pi = 299.85. This gives us the diameter, for the radius simply divide by 2 which is 149.92 :)

An expression involves subtracting two numbers from a given first number under what circumstance will the value of the expressio

vagabundo [1.1K]

Say that you start from a number $x$ . Then, you subtract $y$ and $z$ from $x$ , which means that the expression is

$x-y-z = x-(y+z)$

If we want this expression to be negative, we have

$x-(y+z)$

So, in order for the expression to be negative, the two numbers we are subtracting, combined, must be more than the starting number.

For example, if we start from 10 and we subtract 4 and then 8, we have

$10-4-8 = 10-12=-2$

which is negative, because 4 and 8 combined are more than 10

crimeas [40]

Answer: Two students are the same age but have different heights.

Step-by-step explanation: The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.
