Awheel moves with an angular velocity of 16 radians per second. find the speed of the wheel if its diameter is 28 inches.

Let us gather first all the information:

Let  rad = radians, rev = revolution, 2πr = circumference, r = radius

Radius = 2 8/2 = 14 in

Equation:

Speed of the wheel = 16 rad/sec * rev / 2πr

rad*2πr / rev

We will cancel rad, rev, and 2πr

So here’s left:

Speed of wheel = 16r in/sec

= 16 * 14 in/sec

= 224 in/sec

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
