Question

find the length of the wire required to make four circular rings of radius 14 cm​

Answer 1

Answer:

352cm or 3m 52cm

Step-by-step explanation:

RADIUS GIVEN 14cm

SO, LENGTH OF WIRE IN ONE CIRCULAR RING = CIRCUMFERENCE OF CIRCULAR RING

CIRCUMFERENCE = 22/7*14sq.

= 88 cm

SO LENGTH OF WIRE USED = 88*4

= 352

HENCE, LENGTH OF WIRE REQUIRED TO MAKE FOUR CIRCULAR RINGS IS 352cm

Answer 2

Answer:

Step-by-step explanation:

radius = 14

now taking ,

area of cicle=

22/7×14×14

22/7×196=216

now , a rectangle length is24 so,

area of rectangle =l×b

area of rectangle = area of circle

24×b=216

b=9
