Step-by-step explanation: Explanation: In the process, Diameter= 18, Radius(r)= 18 2 ∴ Radius= 9 Now, Circumference (Perimeter) = ? According to the formula, Perimeter= 2 × 22 7 × r Taking the equation, Perimeter= 2 × 22 7 × r ⇒ 2 × 22 7 × 9 ⇒ 396 7 ⇒ 56.57142857 ⇒ 56.57 Let’s hope this helps you:) Reply
