Question

A well of diameter 140 cm has a stone parapet around it. If the length of the outer edge of the
parapet is 616 cm, find the width of the parapet.​

Answer 1

Answer:

56.1 cm

Step-by-step explanation:

Diameter of well = 140 cm

Radius of well = 70 cm

Circumference of parapet = 616 cm

We know, circumference = π times diameter

Diameter of well - including parapet = 616 / π = 196.1 cm

So, width of the parapet will be

196.1 - 140 = 56.1 cm
