Answer 1

Answer:

The exact circumference of the trampoline is  72.22 ft.

The approximate circumference the trampoline is  72 ft.

Step-by-step explanation:

The given diameter of the trampoline  = 23 feet

Now , Diameter = 2 x RADIUS

⇒ R  = D/2 = 23/2  = 11.5 ft

CIRCUMFERENCE of a CIRCLE  = 2 π R

So, here the circumference of the trampoline  = 2 x π  x (11.5 )

= 2 x (3.14) x (11.5) = 72.22 ft

or, C = 72.22 ft

Now,as the decimal part is 0.22 which is LESS THAN 0.5

⇒ 72.22 ≈ 72 ft

Hence, The exact circumference of the trampoline is  72.22 ft.

The approximate circumference the trampoline is  72 ft.
