Question

The diameter of a wheel is if it rolls covering 10 revolution. Find the distance travelled by it : options

Answer 1

Answer:

Use the formula: c = 2_pi_r, where c is the circumference, r is the radius, and pi can be approximated by 3.14. Following the example, if the car wheel has a radius of 0.3 meters, then the circumference is equal to: 0.3 x 3.14 x 2 = 1.89 meters. Calculate the wheel speed in revolutions per minute.

Answer 2

Answer:

$<marquee>let c=2p..I..r where c= circumference,r=radius pi=3.14,if a car wheel..has a radius of 0.4m then 0.4x3.14x2=2.512meters$
