Easy just find the total of how many people work there then put that no. as a denominator and put 12 on the numerator then times it by 100 and the answer should be 52.2% or 52.17%
The circumference of a circle will be 131.964.
What is circumference of a circle?
The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.
The radius of the circle given is = 21cm
circumference is 2πr = 2*3.142*21 = 131.964cm.
Hence the circumference of a circle 131.964cm.

To answer this question, we must know some identities:
1. cos(x) is an even function, so cos(x)=cos(-x) [this makes choice (c) true]
2. sin(x) and cos(x) are the same periodic functions with a phase-shift of pi/2, so that sin(x+pi/2)=cos(x) [this makes choice (b) true]
3. also, sin(x) is symmetrical about pi/2, and cos(x) is symmetrical about x=0. This means that sin(x)=cos(pi/2-x) [ this case is not present in the choices ]
Answer:
A Linear Expression is the correct choice for this equation
Answer:
Step-by-step explanation:
we know that
<em>Te volume of the cone is equal to</em>
we have
substitute
<em>Te volume of the cylinder is equal to</em>
we know that
To find the volume of the space remaining in the cylinder after the cone is placed inside it, subtract the volume of the cone from the volume of cylinder
so
