Question

Find the circumference.
Use 3.14 for π.
O
r = 6 ft
C = [?] ft
C = πd

Answer 1

37.68 ft

Explanation:

Formula

Diameter = 2r (where r is the radius)

Circumference of a circle = πd (where d is the diameter)

Given:

• π = 3.14
• r = 6 ft

⇒ Diameter = 2 × 6 = 12 ft

Substituting the given values into the formula:

⇒ C = πd

⇒ C = 3.14 × 12

⇒ C = 37.68 ft
