Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.

Answers

Answer:

radius = 6 inches

Step-by-step explanation:

37.68/3.14 = 12 = diameter

radius = 12/2 = 6 inches

Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6

Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04

Answer:
The area of the circle is 113.04 square units

ok this isn’t my answer i found it on quora but it answers ur question u have

We can write a system to solve this problem

Let x= the radius of Circle A

Let y=the diameter of Circle B

x=2y-3

2x+y=49

since we are trying to find the area and the circumference of circle A, we only have to find what x is

x=2y-3 → y=1/2x+3/2

next, we plug in 1/2x+3/2 for y:

2x+1/2x+3/2=49

we can then multiply all the numbers by 2 to get rid of the fractions:

4x+x+3=98

5x+3=98

5x=95

x=19

Circle A radius=19ft

Finally, we solve for the area and circumference:

Area:

A=pi*r^2

A=3.14*19^2

A=1133.54 feet^2

Circumference:

C=2*pi*r

C=2*3.14*19

C=119.32 feet

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.

Answers

Answer:

ok let me try this again

To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.
