Circumference Formula: C = 2πr

• r is radius

Explanation:

Step 1: Define

[Circle] Radius r = 4 in

Step 2: Find Circumference

1. Substitute in r [Circumference Formula]: C = 2π(4 in)
2. [Circumference] Multiply: C = 8π in
3. [Circumference] Substitute in π: C = 8(3.14) in
4. [Circumference] Multiply: C = 25.12 in
5. [Circumference] Round: C ≈ 25 in
