Answer 2

Answer:

The inner diameter is 24 m

Step-by-step explanation:

area of ring = 352 m*2

outer diameter = 32 m

outer radius = 16 m

now , area of ring = π(R*2-r*2). ( r is the inner radius and R is outer radius )

now ,, 352 = π( 16*2 - r*2 )

352 = 22/7 ( 256 - r*2 )

352× 7/22 = 256 - r*2

112 = 256 - r*2

112 - 256 = - r*2

- 144 = - r*2

+ 144 = + r*2

taking square root both side

√144 = √ r*2

12 = r

Inner radius = 12 m

Inner diameter = 12× 2 = 24 m
