Answer 2

QUESTION-:

an object moving in a circular path of radius 2m,covers 2.5 rounds. The distance covered by the object is..

a.34.4m

b.31.9m

c.31.4m

d.34.1m​

EXPLANATION-:

The distance covered will be given by the formula(in 2.5 rounds) -:

$\longrightarrow \underline{\boxed{\bigstar \bf\; Distance=2.5\times 2\pi r }}$

Where ,r is the radius (2 m)

Putting values-:

$\rightarrow \bf\; Distance=2.5 \times 2 \times \frac{22}{7}\times 2\\\\\rightarrow \bf\; Distance=10 \times \frac{22}{7} \\\\\rightarrow \bf\; Distance \approx 31.42$

∴The distance covered is 31.42 metres  [ Opt-c  ]
