Question

A carriage wheel makes 1500 regulations in going over a distance of 4.5 kilometres. Find its radius taking π=3.14

Answer 1

Answer:

Step-by-step explanation:

Dear Student,

● Answer -

r = 47.74 cm

● 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.
