Question

the wheel of has a diameter of 28 cm find the distance covered by the wheel in 20 revolution​

Answer 1

Step-by-step explanation:

Radius= 14cm

no. of revolutions=20

therefore,distance covered

=2πr×no. of revolutions

=(2×22/7×14) ×20

=1760cm

Answer 2

Answer:

Step-by-step explanation:

d=28com

r=d/2=28/2=14cm

Now,

Circumference of wheel=2πr

C=2×22/7×14

C=2×22×2

Therefore,

C=88cm

Now,

Distance covered by wheel in 20 revolutions=C×no of revolutions

Therefore,

Distance=20×88=1760cm=17.6m//
