Question

how much times A wheel of radius 28 cm must rotate to go 352 m​

Answer 1

heya friend...

here's your answer..

____________________________

Radius of the wheel = 28 cm Distance covered by the wheel in one rotation = 2πr = 2 × 22/7 × 28 = 176 cm Distance to be covered = 352 m = 35200 cm Number of rotations of the wheel to cover 35200 cm = 35200/176 = 200

hope it helps you..

Answer 2

IF RADIUS IS 28

28X2=56

SO THE DIAMETER IS 56

SO WHEN ROTATING ONCE 56CM

SO I THINK THIS IS THE ANSWER
