Question

find the distance covered by the wheel of a car in 500 revolutions if the diameter of the wheel is 77cm

Answer 1

in revolution it covers= 2*$\pi$*r=2*22/7*77/2=22*11
in 500 revolutions it covers=500*22*11cm=121000cm

Answer 2

Answer:

120890 cm

Step-by-step explanation:

Diameter of the wheel = 77 cm

Radius of the wheel = $\frac{77}{2}= 38.5 cm$

Circumference of Wheel = $2\pi r$

                                          = $2 \times 3.14 \times 38.5$

                                          = $241.78 cm$

Distance traveled in 1 revolution= 241.78 cm

Distance traveled in 500 revolutions= $241.78 \times 500$

                                                            = $120890 cm$

Hence the distance traveled in 500 revolutions is 120890 cm
