Question

The diameter of the wheel of a heavy vehicle is 91cm. Find the distance traveled by the vehicle when the wheel rotates 1000 times​

Answer 1

Answer:

The distance travelled by the vehicle when the wheel rotates 1000 times is 2860 m.

Step-by-step explanation:

Given :

Diameter of wheel (D ) = 91 cm.

Radius of wheel (R) = D /2 = 91/2=45.5 cm.

Distance travelled by the vehicle when the wheel complete 1 revolution = circumference of the wheel which is a circle

∴ Distance travelled by the vehicle when the wheel rotates 1 time= 2$\pi$R

                                                        = 2 × (22/7) × 45.5 ( where $\pi$ = 22/7)

                                                      = (2 × 22×45.5 ) /7=2002 /7= 286 cm.

Distance travelled by the vehicle when the wheel rotates 1000 times = 286 × 1000 = 286000 cm.

 100 cm = 1 m.

1 cm. 1/100 m.

286000 cm. 286000 / 100m.= 2860 m.          

                                                                                           

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Diameter of wheel (D ) = 91 cm. Radius of wheel (R) = D /2 = 91/2=45.5 cm. = (2 × 22×45.5 ) /7=2002 /7= 286 cm. Distance travelled by the vehicle when the wheel rotates 1000 times = 286 × 1000 = 286000 cm.
