Question

the circumference of a circular metal sheet is 44 cm, find the area of the sheet.​

Answer 1

Answer:

154 cm sq.

Step-by-step explanation:

Circumference = 2 pi R = 44

⇒ pi R = 44 / 2 = 22

⇒ R = 22 / pi

       = 22 / (22/7)

       = (22/22) * 7 = 7

⇒ R = 7

Area = pi R^2

        = 22 * 7 * 7 / 7

        = 22 * 7 = 154 cm sq.
