I’ll help you out, but what are the numbers in between? Like does it go boy 0, .3, .6, .9, to 1? Or is there a different pattern
Area of the first circle = 16(pi)
We know that
Area of a circle = (pi) * (Radius)^2
Then
16(pi) = (pi) * (radius) ^2
(4)^2 = (Radius)^2
Radius = 4
Diameter = 8
Circumference = (pi) * Diameter
= 8(pi)
In case of the second circle
Area = (pi) * (Radius) ^2
25(pi) = (pi) * (Radius)^2
(5)^2 = (Radius)^2
Radius = 5
Diameter = 10
Circumference = 10(pi)
So
Circumference of first circle:Circumference of second circle = 8(pi):10(pi)
= 4:5
It depends what is the second equation
You spent 40% of your budget.
10/25=2/5=40/100
No, 14 is the gcf of 42 and 154.
