Answer: This coil will not be enough to complete the job.
Step-by-step explanation:
The circumference of the coil of wiring can be calculated with:

Where r is the radius and 
The radius can be calculated by dividing the diameter by 2. Then:

Convert 9 inches to yards (1 yard=36 inches):

Substitute this radius into the formula:

Since there are 21 circles of wire, you need to multiply
by 21:

The coil has 32.97 yards of wire and Alex needs 34 yards, therefore, this coil will not be enough to complete the job.
The question is missing the figure. So, it is attached below.
Answer:
Area of the shaded sector is <u>144π units squared</u>.
Step-by-step explanation:
Given:
Central angle of the sector is, 
Radius of the circle is, 
We know that, area of a sector of a circle of radius 'R' and central angle
is given as:

Plug in
. This gives,

Therefore, the area of the shaded sector is 144π units squared.
Hi there!
First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.
When we know 18% of the price, we can also find 1% of the total price.
18% = $13.23
Divide both sides by 18.
1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.
100% = $73.50.
Therefore, the original price for the coat is $73.50.

This is a typo and vaguely phrased. However, the closest to a direct solution is to think of it as follows: 35% of the cars are speeding. Out of these, 52% of the cars are also speeding. Hence, the result of cars that are both speeding and speed cars is 0.52*0.35=0.182
