Question

An umbrella has 12 ribs which are equally spaced. Assuming umbrella to be a flat circle of

radius 28cm, Find the area between consecutive ribs of the umbrella. Provided that π = 3.14.​

Answer 1

Step-by-step explanation:

circumfrence of circle is 2πr and as radius is given therefore we can calculate as such and now divide it by 12 you will get the answer therefore circumfrence is 2×3.14×28 = 175.84/12 = 14 degree is the space
