The circumference of the circle is given as 2r where is a constant whose value is equal to 22/7 and r is the radius of the circle

From the given problem, we have the circumference =37.7

2r = 37.7

2*22/7*r = 37.7

r = 37.7*7/(22*2)

r = 263.9/44

r = 5.99

r = 6cm

Radius = 6 centimeters (Rounded to nearest whole number)

## Solution 2

37.7 = 2 x pi x r
18.85 = pi x r
r = 18.85/pi
or
r = 6

Hope this helps

Question
The area of a circle is 452.39 ft^2 . Why would the diameter have to be?
Solution 1
I believe it would be 24ft.
Solution 2
STEP 1:

Area=πr^2
plug in the known numbers

452.39= (3.14)r^2
divide both sides by 3.14

452.39 ÷ 3.14= r^2

144.07= r^2
take the square root of 144.07 and r^2

12 feet= r

STEP 2:
multiply radius by 2 to equal diameter

Diameter= Radius * 2
Diameter= 12 feet * 2
Diameter= 24 feet

ANSWER: The diameter would be 24 feet.

Question
the student council set a goal of raising at least $500 in flower sales. so far it has raised$415 .write an inequality to show how many more dollars, d, the student council needs to reach its goal
Solution 1

Step-by-step explanation:

Let d be the number of dollars needed by students council to reach its goal.

Given: The student council set a goal of raising at least ( less than or equal to ) $500 in flower sales. Currently, the student council raised the amount =$415

Now, the inequality to show the number of more dollars, d, the student council needs to reach its goal is given by :-

Solution 2
415 + d ≥ 500

I believe that's the inequality since they want to raise a minimum of $500 so that means it can be more than$500. Hope I helped.
Question
A computer store builds custom computers by allowing customers to choose 1 of 4 different CPUs, 1 of 8 hard drives, and 1 of 3 videos cards. How many different computers are possible?
Solution 1
There are 96 possible combinations.

The fundamental counting principle states that the number of total options is given by multiplying the number of possibilities for each option, or
Total choices = choices x choices x ...

4*3*8 = 96
Question
The ratio of students in Jaime's class who have a dog or cat at home to those who don't is 12:8. What percent of the class do NOT have a dog or cat at home?                                PLEASE SHOW ALL WORK! (A) 33 1/3% (B) 40% (C)60% (D) 66 2/3%
Solution 1
Given:
Ratio of students with dog or cat to students without dog or cat.
12 : 8

12 + 8 = 20

20 is the 100%

12/20 = 0.60 x 100% = 60% with dog or cat

8/20 = 0.40 x 100% = 40% without dog or cat ANSWER IS B.

Question
Rewrite this function in the form that reveals the minimum of the function. c(p)=p^2-28p+250
Solution 1
Given that the function is given by:
c(p)=p^2-28p+250
The minimum value of the function is at the derivative of c'(p)
thus from the function given:
c(p)=p^2-28p+250
c'(p)=2p-28
Thus the minimum function is c'(p)=2p-28
