Question

How many times a wheel of radius 35cm must rotate to go 286m ? answer of this question is -130.

Answer 1

radius = 35 cm
total distance= 286m = 28600cm

distance travelled in one round = circumference of a wheel= 2πr

circumference of a wheel= 2× 22/7× 35
circumference of a wheel= 220 cm

Number of times a wheel rotate= Total distance/ distance travelled in one round

number of times a wheel rotate = 28600/220
= 130
Wheel rotates 130 Times

Answer 2

Radius :- 35 cm (Given)

Total distance :- 286 m (Given)

= 28600 ( ; 1m = 100cm)

Distance travelled in one round = Circumference of a wheel = 2*pi*r

Circumference of a wheel = 2*22/7*35 cm

Circumference of a wheel = 220 cm

Number of times a wheel rotates = Total distance/Distance travelled in one round.

Number of times o wheel rotates = 28600/220 = 130

Hence, wheel rotates 130 times to go 286m

Answer 3

Radius :- 35 cm (Given)

Total distance :- 286 m (Given)

= 28600 ( ; 1m = 100cm)

Distance travelled in one round = Circumference of a wheel = 2*pi*r

Circumference of a wheel = 2*22/7*35 cm

Circumference of a wheel = 220 cm

Number of times a wheel rotates = Total distance/Distance travelled in one round.

Number of times o wheel rotates = 28600/220 = 130

Hence, wheel rotates 130 times to go 286m

Answer 4

Radius :- 35 cm (Given)

Total distance :- 286 m (Given)

= 28600 ( ; 1m = 100cm)

Distance travelled in one round = Circumference of a wheel = 2*pi*r

Circumference of a wheel = 2*22/7*35 cm

Circumference of a wheel = 220 cm

Number of times a wheel rotates = Total distance/Distance travelled in one round.

Number of times o wheel rotates = 28600/220 = 130

Hence, wheel rotates 130 times to go 286m
