Answer:
132 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi*r
Using 22/7 as pi
C = 2 * 22/7*21
= 132 cm
Answer:
Euclid fifth postulate gives information regarding parallelism of lines.Euclid's fifth postulate states If a straight which falls on two straight lines makes interior angle on the same side of it.And if sum those two interior angles is less than 180° ,then two straight will not be parallel which means they if they produced indefinitely they will surely meet on the side where some of interior angles is less than 180°.
This postulate is more complex as compared to other four postulates.It says that two parallel lines never meet.This postulate is also known as parallel postulate.
