Question

covered when it has made 8000 revolutions,
6. A carriage wheel makes 1500 revolutions in going aver a distance of 4.5 kilometres
Find its radius taking it = 3.14.​

Answer 1

Answer:

Step-by-step explanation:

Let r be radius and c be circumference of circle. Carriage wheel travels 4.5 km = 4500 m.

Circumference of circle is calculated by -  

c = 4500 / 1500

c = 3 m

But we know,  

c = 2πr

r = c / 2π

r = 3 / (2 × 3.142)  

r = 0.4774 m

r = 47.74 cm

Hence, radius of the carriage wheel is 47.74 cm.
