Question

a boy in and around a circular Park 10 times if the diameter of Park is 280 M find the distance covered by the boy in kilometre

Answer 1

Heya Frnd. ........☺

Dist. covered by the boy = 10 × circumference of the park.

Diameter of path = 280 m

Now,

$= 10 \times 2 \: \pi \: r$

$= \: 10 \times 2 \times \frac{22}{7} \times \frac{1}{2} \times 280$

$= 220 \times 40$

$= 8800 \: m$

$= \: 8.8 \: km \: ...........ans$

Answer 2

hiii!!!

here's ur answer...

given the diameter of the circular park=280m

therefore radius=280/2

=140m

circumference of the circular park=2πr

=2×22/7×140

=44×20

=880m

if the boy runs 10 times around the park then the distance covered by him is=880×10

=8800m

in km=8800/1000

=8.8km

hence, final answer is 8.8km

hope this helps..!
