Answer:
Circumference of circle 1 : Circumference of circle 2 = 1 : 2
Step-by-step explanation:
Circumference of a circle = πD, where D is the diameter.
Diameter of circle 1 = 1.125
Circumference of circle 1 = π x 1.125
Diameter of circle 1 = 2.25
Circumference of circle 1 = π x 2.25
Circumference of circle 1 : Circumference of circle 2 = 1 : 2
Don’t mind me just stealing points
The answer for what the ratio is for 4% is 4:100
When you multiply powers, add the exponents.
When you divide powers, subtract the exponents.
When you raise a power to a power, multiply the exponents.
Anything to the zero power equals one.
When you have a negative exponent, flip it and make it positive.
