Answer 1

Hi!!

This is a simple answer which you can write in exam.

☀Diameter=98cm

:. Radius=(98/2)cm. =49 cm

:. Circumference=$2\pi \: r$
$= (2 \times \frac{22}{7} \times 49)cm \\ = (44 \times 7)cm \\ = 308 \: cm$

:. Distance covered in 1 run =308 cm

:. Distance covered in 2000 runs $=(2000 \times 308)cm \\ = 616000 \: cm \\ = 6.160 \: km. Ans \:$
