A circle has a diameter of 12 inches. what is the area of the shaded section. use 3.14 as pi. no a,b,c,d just an exact answer thanks


Answer 1


Area of shaded section is 113.04

Step-by-step explanation:

Area of circle is calculated by formula A=\pi r^(2).

where 'r' is radius.

here given diameter is 12 inches .

so radius is calculated as  r=(d)/(2)=(12)/(2)=6

and value of \pi is 3.14

so, Area is ;

A=\pi r^(2)

Put value of \pi =3.14 and r=6 inches




Hence, area of shaded section is 113.04

Answer 2
Answer: A = pi r ^2
A = 3.14(6^2)
A= 3.14 (36)
A = 113.04

The reciprocal of a fraction less than 1 is always a fraction greater than 1. Why is this?


Let's see, an example of a reciprocal of a fraction less than 1 would be something like this: 1/8, after the reciprocal it will become 8/1.
8/1 equals 8 therefore is larger than 1.

This will always happen because as long as the denominator(the bottom) is larger than the numerator, the reciprocal(flipping the numbers) will make it larger than 1.
Here are some examples of reciprocals: 1/2 becomes 2/1.  1/3 becomes 3/1. 1/4 becomes 4/1.  Just swap the two numbers and the number that it becomes will be automatically larger than 1.

A chef cooked 5 kg of mashed potatoes for a dinner party. If the guest ate only 1/12 of the amount he cooked. How much did the eat?


to do this we have to multiply 5 times 1 1/2. We can write 1 1/2 as an improper fraction which will be 3/2. We can write 5 as 5/1 and multiply across with 3/2. This will be 15/2 or 7 1/2 as a mixed fraction.

Everbank Field, home of the Jacksonville Jaguars, is capable of seating 76,867 fans. The revenue for a particular game can be modeled as a function of the number of people in attendance, x. If each ticket costs $161, find the domain and range of this function.


maximum seating 76,867 fans
cost of tickets $161
revenue: f(x) = 161x

y = 161x  

domain is the x values
range is the y values

using the formula: y = 161x where x = 76,867
y = 161(76,867)
y = 12,375,587

domain is 76,867
range is 12,375,587

HELP BRANLIEST AND 15 POINTS The director of a local ballet company needs to print the programs for the next performance. Janet’s Print Shop charges $0.25 per program plus a $35 set-up fee. The Printing Press charges $0.15 per program plus a $50 set-up fee.
Which printing company offers the better deal if 200 programs are printed? Explain your reasoning.
​Find the number of programs for which the total costs are the same. Explain how you determined the number of programs.



the Answer For Part A:

The Company that offers the better deal is The Printing Press since if we do 0.15 * 200 + 50 = $80 versus Janet’s Print Shop that charges $85 in total as we can see by the problem 0.25 * 200 + 35 = $85

Step-by-step explanation:


the total cost of 200 copies at a rate of 0.25 cents a copy with a $30 are the same when 233 copies are ordered at 0.15 cents per copy plus the $50 set up fee.

Step-by-step explanation:

We can find the answer to this by comparing the prices:

200 x $0.25 + $35 = $85 this can be written in function notation as

f(x) = 200x + 35

If X = .25 then:

f(0.25) = 200(0.25) + 35 = 85

Using this same equation we can see that

f(0.15) = 200(0.15) + 50 = 80

Now we simply need to divide the difference between the two amounts by 0.15 to find the answer: 5/0.15 = 33.3--

The answer represented by an inequality is 200 < x < 233.

Terry uses 3 cups of pumpkin seeds to decorate the tops of 12 loaves of bread. She puts an equal amount of seeds on each loaf. How many cups of pumpkin seeds does she put on each loaf of bread. Show calculation.


3 cups do 12 loaves
12 / 3 = 4
so 1 cup does 4 loaves
1/4 = 1/4 or 0.25 (take your pick)

So she needs 1/4 of a cup per loaf

How do I solve 4x + 3y=0 & 2x + y = -2 using substitution


4x + 3y = 0
2x + y = -2
take 2x and subtract to the side with -2
it'll look like this: y = -2x - 2
plug that equation in where the y is in the other equation.
it'll look like this: 4x + 3(-2x - 2)=0
which you multiply 3 and the -2x and the -2
which the equation would be: 4x - 6x - 6=0
put together like terms: -2x - 6=0
add the 6 to the side with the zero: -2x = 6
divide both sides by -2 which x= -3
to get y you plug in the answer for x (-3)
2(-3)+y= -2
so it'd then be -6 + y = -2
add the -6 to the side with -2
y= -2 +6
y= 4
so your complete answer is ( -3, 4)
