Question

The diameter of a cycle wheel is28 cm .How many revolution will it make in moving 11 km.​

Answer 1

Answer:

125

Step-by-step explanation:

perimeter=2*pi*14=88cm

no or revolutions =11000÷88 =125

Answer 2

125 revolution will it make in moving 11 km.

Step-by-step explanation:

given diameter is 28cm

as we know,

perimeter of circle=2πr

=2×22/7×28/2

=88

now,

11km=11000cm

so, 11000/88=125

hence, 125 revolutions would need to complete 11 km
