Question

find the area and perimeter of the circular field with diameter 4.2 *10^-2

Answer 1

Answer:

Step-by-step explanation:

DIAMETER  = 4.2*10⁻² M

RADIUS = DIAMETER /2

              = 4.2/2 *10⁻²

              = 2.1*10⁻² M.

AREA = πR²

          = 3.14*2.1*2.1*10⁻⁴

          = 13.847 *10⁻⁴ M².

PERIMETER = CIRCUMFERENCE = 2πR

                                                       = 2*3.14*2.1*10⁻²

                                                       = 13.188 *10⁻² M.

THEREFORE THE AREA OF THE CIRCULAR FIELD IS 13.847*10⁻⁴ M² AND THE PERIMETER OF THE CIRCULAR FIELD IS 13.188*10⁻²M.

HOPE THIS HELPS.
