Question

if a wheel covers a distance of 440 in 20 rotation then the diameter of the wheel is (take r=22/7)​

Answer 1

Step-by-step explanation:

Let r be the radius of the wheel. Then,

Let r be the radius of the wheel. Then,Diameter = 84 cm

Let r be the radius of the wheel. Then,Diameter = 84 cm2r=84

Let r be the radius of the wheel. Then,Diameter = 84 cm2r=84r=42 cm

Let r be the radius of the wheel. Then,Diameter = 84 cm2r=84r=42 cmCircumference of the wheel = 2πr=264cm=2.64m

Let r be the radius of the wheel. Then,Diameter = 84 cm2r=84r=42 cmCircumference of the wheel = 2πr=264cm=2.64mSo, the wheel covers 2.64 meters in one complete revolution.

Let r be the radius of the wheel. Then,Diameter = 84 cm2r=84r=42 cmCircumference of the wheel = 2πr=264cm=2.64mSo, the wheel covers 2.64 meters in one complete revolution.Total number of revolutions in covering 792 meters =
