A car travels 1 km distance in which each wheel makes 450 complete revolutions. Find the radius of wheel.
рдЙрддреНрддрд░
Let radius of wheel = ‘r’ m
Circumference of wheel = (2ЁЭЬЛr)m.
No. of revolutions = 450
Distance for 450 revolutions = 450 × 2ЁЭЬЛЁЭСЯ = 900ЁЭЬЛЁЭСЯ ЁЭСЪ
distance travelled = 1000 m.
900ЁЭЬЛr = 1000
r = 10000 9ЁЭЬЛ × 100
`=10/(9pi)` ЁЭСЪ
=`1000/(9pi)` ЁЭСРЁЭСЪЁЭСа
ЁЭСЯЁЭСОЁЭССЁЭСЦЁЭСвЁЭСа (ЁЭСЯ) =`1000/(9pi)`ЁЭСРЁЭСЪЁЭСа
