Question

4) Two circles have diameters in the ratio
1:3. Find the ratio of their circumferences​

Answer 1

Answer:

1:3

Step-by-step explanation:

let d be the diameter of the circle with diameter 1.

circumference = ($\pi$d)

circumference of other circle = ($\pi$3d)

thus ratio is still 1:3

Answer 2

Answer:

THIS UR ANSWER

Step-by-step explanation:

diameter of the first circle be x

radius of the first circle be x/2 unit

diameter of the second circle be 3x

radius of the second circle be 3x/2

∴ratio=2x/2 : 23x/2

        =x:3:x

        =1:3

hence, 1:3 is the required ratio.
