Question

Find the perimeter of given figure​

Answer 1

Answer:

perimeter of circle =2×22/7×r

where r = 2.1m

=2×22/7×2.1

2×22×0.3

44×0.3 =13.2

therefore perimeter of total figure is 13.2 metre

as 1/4th part is missing,3/4 part is present

there fore 13.2 ×1/4=3.3m

13.2m - 3.3m =9.9m

Answer 2

Answer:

15.1

Step-by-step explanation:

radius of given circle is equal to 2.1 m

therefore its perimeter = 2πr

= 13.2m

now, in the circle quarter part is removed.

therefore, total perimeter - 1/4 perimeter = 13.2 - 3.3

=10.9m

now, add the given 2.1 + 2.1 radius

= 15.1m
