Question

a garden is in the shape of semi circle pf radius 42 m . A person jogs around the garden 3times .What is the distance jogged by him

Answer 1

Perimeter of semi circle = πr + d = 22/7 *42 + 84

132 + 84= 216m

so, distance jogged = 216m

Answer 2

Garden is in the shap of Semi-circle,

therefore peirmeter of Semi-circle is=πr/2=πr
=22*42/7m = 32m;

and persona jogged by 3 times around garden=3*132=396m (answer);
