The circumference (C) of any circle is the perimeter around it; it is circles' one dimensional measurement (i.e. in, ft, cm, mi, etc.). As a circle grows, increasing the
circle's size, the distance around it (circumference) increases proportionately with
the radius. Thus this length can be found by multiplying the radius × 2 (or diameter × 1) × a constant known as pi. Pi, an infinitely long decimal that begins 3.1416, was calculated by working backwards from the length of a circle, divided by 2×radius. No matter the size of any circle, they discovered that the distance will always vary 3.1416... × twice the radius (or diameter). An example is a circle of radius 40 cm: C = 2pi×r = 80pi cm, or 251.33 cm.

The area (A) of a circle, however, covers much more matter; it is the two dimensional measure of any circle (i.e. sq.in., sq.ft, sq.cm, etc.). Area also varies according the constant pi × the radius, BUT it increases much more than the radius once; it varies by the radius × radius (radius squared) × the value pi. Using the same circle example of radius 40cm: A = pi×r^2,
A = (40×40)pi = 1600pi = 5,026.55 cm^2.

So you can see that the [2-dimensional] area of this circle is 20 times the [1-dimensional] circumference

Answer:

C

Step-by-step explanation:

The formula for the area of a trapezoid is: \frac{1}{2} (height)(sum of parallel lines)  

Thus, the formula in this question would be: \frac{1}{2} (4)(4+8) which is option C

m_a_m_a [10]

Answer:

$33

Step-by-step explanation:

From the question, $22 is correct

If Helen Ming receives travel allowance of $220 from her company for time away from home

She has a 10% income tax rate

The amount she has to pay in taxes for the employee benefits is

10% of $220

10/100*$220

=0.1*$220

=$22

So you are correct

The only reason why you could be wrong is if the question is different from what you posted above just like the below question

Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable and she has a 15 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?

Here the amount she has to pay for the employee benefits is

15% of $220

15/100*$220

=0.15*$220

=$33
