Question

The diameter of a bicycle wheel is 75 centimeters. How far does the bicycle travel when the wheel makes 29 revolutions? Use 3.14 as an approximation for pie

Answer 1

Answer:

68.295 m or 6829.5 cm

Step-by-step explanation:

diameter = 75 CM

so,

radius = 75/2 CM

now

circumference of a circle = 2πr

=> 2 × 3.14 × 75/2

=> 3.14 × 75

=> circumference = 235.5 CM

now

number of revolutions = 29

so

total distance travelled by the bicycle =

29 × 235.5 = 6829.5 cm

Or

in meters => 6829.5 / 100 = 68.295 m

Answer 2

Answer:

⇒diameter of a bicycle wheel is 75 centimeters

⇒the bicycle travel when the wheel makes  revolutions so

⇒Distance covered by bicycle in one  revolutions = 2πr

where r is radius of  bicycle

⇒Distance covered by bicycle in 29 revolutions = 29 * 2πr

⇒ 29 * 75 *3.14

⇒6829.5 cm
