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%.

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
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
