Answer:
The ratio is 1:3
Step-by-step explanation:
People can do this in different ways.
Firstly, set some variables for cydlinder A:
Diameter = 18
Height = 1
Radius = 18 ÷ 2 = 9
Area of a cylinder is [tex]\pi r^{2} h[/tex]
Plug values in:
[tex]\pi 9^{2} 1[/tex] = 81π
Cylinder B:
Diameter = 18 ÷ 3 = 6
Height = 1 * 3 = 3
Radius = 6 ÷ 2 = 3
[tex]\pi3^{2}3 = 27\pi[/tex]
Cylinder b is 3 times less than cylinder a:
81π ÷ 27π = 3
So that means three lots of cylinder b is equal to one of cylinder a.
Meaning the ration is 1:3
Hope this helps!
