**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.**
