Question

7) The diameter of circular garden is 49 m. Find the distance

covered by a runner if he makes 2 rounds round the

garden.

Answer 1

diameter is 49 then radius will be 24.5m
circumstance = 2πr
putting the equation in this formula we get 154m but it is 1 round distance for 2 round distance we multiple 154by 2 then we get 308 answer

Answer 2

diameter of the circle is 49m
so, radius is 49/2 =24.5
circumference=
$2\pi \: r$
22/7×24.5×2
=22×7
=154
it is said that to complete two rounds
so,154×2
=308m
