Question

the diameter of a cycle wheel is 70cm.how far will it go in 24 revolution​

Answer 1

Step-by-step explanation:

diameter =70cm

raidus =35cm

circumference of 1 revolution =2πr

=2×22/7×35

=2×22×5

=110×2=220cm

total distance in 24 revolution =220×24 = 5280cm

Answer 2

Answer:

Distance covered in 24 revolution is 5280 cm.

Step-by-step explanation:

Diameter of circle(D)=70 cm.

Radius (r)=D/2

               =70/2=35 cm.

Distance covered in 1 revolution=circumference of circle=2$\pi$r

Distance covered in 24 revolution =24×2$\pi$r

                                                        =24×2×(22/7)×35      (value of $\pi$=22/7)

                 

                                                       =5280 cm.
