Question

Find the circumerference

Answer 1

Circumference = diameter x PI

Circumference = 8 in x Pi

Circumference = 8PI in. (Exact)

Or as a decimal answer: 25.12 in.

Answer 2

25.1 in (nearest tenth)

Explanation:

Formula

Circumference = πd (where d is the diameter)

From inspection of the diagram:

• Diameter (d) = 8 in

⇒ Circumference = 8π

= 25.1 in (nearest tenth)
