Question

10. How much distance will be covered by Swathy, if she runs through a circular foot path of diameter 7m. ​

Answer 1

$\Large\sf\underbrace{Question:}$

How much distance will be covered by Swathy, if she runs through a circular foot path of diameter 7m. 

$\sf\Large{\underline{\underline{Answer:-}}}$

We know,

Diameter of circular path = 7m

FIND:-

• The distance covered by Swathy.

⠀

So,

First, we need to find the radius of circular path by using this formula -

$r = \frac{d}{2}$

$r = \frac{7}{2}$

r = $\sf{\cancel\dfrac{7}{2}}$ = 3.5 m.

Now,

we know that,

$circumference = 2\pi \; r$

Substitute the values,

$2 \times \frac{22}{7} \times 3.5$

$\sf{\cancel\dfrac{154}{7}}$ = 22m.

Since, Circumference = 22m

∴ Swathy will run 22m.
