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)**

37.7 = 2 x pi x r

18.85 = pi x r

r = 18.85/pi

or

r = 6

Hope this helps

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:

Find the radius.

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.

Hope this helps! :)

Question

Which is a good comparison of the estimated sum and the actual sum of seven nines twelfth plus two and eleven twelfth

Solution 1

That will be 12×11=132. 7×9=63. 63×12=756. 756+2=758. actual sum = 758. estimated sum = 800

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

**Answer: **

**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

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.**

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% =

Question

11 more than a number q is negative 15

Solution 1

Q = -26

work : 11 + q = -15

q = -15 - 11

q = -26

work : 11 + q = -15

q = -15 - 11

q = -26

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

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

Question

The amount of money you earn varies directly with the number of hours you work. You work for 8 h and earn $98. How many hours do you need to work to earn $441?

Solution 1

First find the Unit Rate by dividing 98/8 which is : $12.25 per hour. Then divide $441 by $12.25. The answer is 36. **You would have to work 36 hours to earn $441.**
