Question

Find the distance covered by a motorbike if its tyres are of radii 14dm and each and took 7500 Revolution to cover the distance.

Answer 1

Answer:

so the 14 dm = 1.4 meter

circumference=2*22/7*r

                       =2*22*0.2

                       =8.8m^2

since the tire made 7500 revolution

8.8 * 7500 = 66000 m^2

so the 66000 meter of distance is covered

Answer 2

Distance covered is  6600000 cm

Step-by-step explanation:

Radius of wheel of bike = 14 dm

1 dm = 10 cm

14 dm =$14 \times 10 = 140 cm$

Circumference of wheel = $2\pi r = 2 \times \frac{22}{7} \times 140 = 880 cm$

Distance traveled in 1 revolution = 880 cm

Distance traveled in 7500 revolution = 880 \times 7500 = 6600000 cm

Hence distance covered is  6600000 cm
