First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65=85.722 and 2*3.14*11.25=70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.
centre of the circle =Midpoint of the diameter
centre of the circle=

radius of the circle=

equation of the circle: (x+2)²+(y-3)² = 40
ie.. x²+4x+4+ y²- 6y+ 9=40
ie... x²+y²+4x-6y-27=0
this is the answer......
Answer:
91 cents
Step-by-step explanation: 3 times 25 is 75
3 times 5 is 15 then 1 so add to together
Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3
