Question

Inner circumference of a circular path is 440 m width of the path is 14 m. Find diameter of the outer circle of the circular path. solve plz note book plzzz solve​

Answer 1

Step-by-step explanation: Solution :----- let radius of inner circle is = x cm

than radius of outer circle = (x+14)cm (as path is 14cm in width)

A/q,

Let inner radius be r metres.

Then,

2πr = 440 [circumference =2πr]

r = 440×7/44 = 70 m.

Radius of outer circle = (70 + 14) m = 84m [inner radius +track wide]

diameter of the outer circle of the track 2*84 =168 m [dia=2* radius]

Ans =168m
