Question

the diameter of a wheel of cycle is 21 cm how far it will go in 500 revolutions

Answer 1

R = 21/2

P = 2piR = 2 * 22/7 * 21/2

P =66cm

500 revolutions = 66 * 500 = 33000 cm = 330m

Hence it will go 33000cm or 330m far in 500

Answer 2

Answer:

Step-by-step explanation: circumfrence of wheel =22/7*21

=66cm

therefore in 500 revolution =500*66 =33000cm
