Question

A wheel has diameter 84 cm. How many complete revolutions it should
take to cover 792 meters.​

Answer 1

Answer:3

Step-by-step ,xplanation:

Given that, Distance=792 m

Diameter= 84 cm

Revolution=Distance÷Perimeter

Radius=84÷2=42m

Perimeter=2πr

              =2×22/7×42

              =264m

Revolution=792÷264

                 =3
