Question

A garden is in the shape of a semi cirle of redius 42 m. A person jugw around of the garden 3 times. What is tha distance jugged by him?

Answer 1

Answer:

The correct answer is $648 \; m$.

Step-by-step explanation:

As the garden is in a semicircular shape, therefore,

Radius of garden $= 42 \; m$

As we know that,  

Circumference of semicircle $= \pi r$

Whereas, $r$ is the radius

Therefore,

Distance to walk all around the ground $\left( d \right)$-

$d = \pi r + 2r$

$d = \frac{22}{7} \times 42 + 2 \times 42$

$d = 132 + 84 = 216$

As the person jugged around of the garden $3$ times.

Therefore,

Distance jugged by the person $= 3 \times 216 = 648 m$.

Hence the distance jugged by the person is $648 m$.
