 Q. A skating champion moves along the circumference of a circle of radius 28 m in 44 sec. How many seconds will it take her to move along the perimeter of a hexagon of side 48 m?
 ✖ A. 90 ✖ B. 84 ✖ C. 68 ✔ D. 72

Solution:
Option(D) is correct

Circumference of the circle = $2\pi r=2\times \dfrac{22}{7}\times 28=176$ m

Given, side of the hexagon =48 m

So, perimeter of the hexagon = $48×6=288$ m

Skating champion moves 176 m in 44 sec

Skating champion moves hexagon (288m) in:

$=\dfrac{44}{176}\times 288$

72 sec
