Question

A garden is in the shape of a semi-circle of radius 42 m.
What is the distance jogged by him?​

Answer 1

Answer:

the distance jogged by him is =132m

Answer 2

Answer:

The distance jogged by him is 216m.

Step-by-step explanation:

Circumference of Circle = 2πr.

Radius,r = 42m.

So, Circumference :

$= 2\pi \: r \\ = 2 \times \frac{22}{7} \times 42 \\ = 2 \times 22 \times 6 \\ = 264$

Semi-circle = Circumference / 2

= 264/2

= 132m

Perimeter of Semi-circle :

= Half of Circumference + Diameter

= 132 + (42*2)

= 132 + 84

= 216m
