Question

the wheels of a car are of diameter 80 cm each. how Many distance covered in 680 revaluations​

Answer 1

Answer:

• 170965.6 cm

Step-by-step explanation:

Given

• Diameter = 80 cm
• Radius = Diameter/2
• Radius = 40 cm

To find

• Distance covered in 680 revolutions.

Solution

Distance travelled in one revolution = 2πr

• 2 × 22/7 × 40
• 44/7 × 40
• 251.42 cm

Now,

• 680 - 680(251.42)
• 680 - 170965.6

Hence,

Distance covered in 680 revolutions is 170965.6 cm.
