A circular track has an inner circle of radius 28 m and an outer circle of radius 35 m. Deepa runs once around the inner edge and Farah runs once around the outer edge. How much farther (in metres) does Farah run than Deepa? (Take π = 22/7)

Question

Accepted Answer

44. Outer C = 2*22/7*35 = 220 m; Inner C = 2*22/7*28 = 176 m. Difference = 220 - 176 = 44 m.

A circular track has an inner circle of radius 28 m and an outer circle of radius 35 m.
Deepa runs once around the inner edge and Farah runs once around the outer edge.
How much farther (in metres) does Farah run than Deepa? (Take π = $\frac{22}{7}$ )
