Question

Find the circumference of the object. Use 3.14 or 22 7 for ml. Diameter:9​

Answer 1

C ≈ 28.26 cm

Explanation:

The circumference (C) is calculated as

C = πd ( d is the diameter ) , then

C = π × 9 ≈ 3.14 × 9 = 28.26 cm ( to the nearest hundredth )

Answer 2

c = 28.26 cm

Explanation:

equation for circumference of a circle is 2πr

r = d/2 so here r = 9/2 = 4.5

2 x 3.14 x 4.5 = 28.26
