Answer:

Step-by-step explanation:

Answer 2

Answer:

The diameter of the given field is 21 metres.

Given:

Neha has to run 66 m in making two complete revolutions round a circular field  

To find:

The diameter of the field

Solution:

Circumference of a circle is the distance around it. It is the length of the circle if it were opened and straightened into a line segment.  

Circumference = 66 m

By formula, Circumference = 2πr  

66 = 2$\pi$ r

r = 10.5 m

Diameter = 10. 5 $\times$2 = 21 m
