Answer 1

Answer:

I think 220 m is your answer . Hmmmmm

Answer 2

Answer:

140 cm

Step-by-step explanation:

The circumference of a circle is 2πr where r is the radius.

and, 2πr = 440 cm.

therefore, equation =

2πr = 440

⇒ 2×22/7×r = 440

⇒22/7×r = 220

⇒r = 220×7/22

⇒r = 70 cm

diameter = 2r = 2×70 = 140 cm.
