Question

Circumference of a circle is 88cm. Find its diameter​

Answer 1

Answer:

the diameter of sum is 28cm

Step-by-step explanation:

the formula of circumstance of circle is 2πr

2πr=88cm

2×22/7×r=88

22/7×r=44

22×r=44×7

22×r=308

r=308÷22

r=154÷11

r=14cm

radius =diameter÷2

diameter = radius×2

diameter = 14×2

diameter = 28cm
