Question

Answer it i called you genius -______
the ratio of the outer and inner perimeter of a circular path 23:22 if the path is 5 metre wide then what is diameter of circle is give me solution

(a)55m
(b)110m
(c)220m
(d)230m

Answer 1

Answer:

220m

Step-by-step explanation:

Let R and r be the outer and inner radii of the circular path.( now see pic)

Let R = 23x and r = 22x

It is given that the width of the path is 5 m wide

∴ R – r = 5 m

⇒ 23x – 22x = 5 m

⇒ x = 5 m

Thus, the external diameter of the circular road = 2 × 23 × 5 m = 230 m and the internal diameter of the circular road = 2 × 22 × 5 m = 220 m
