What is the area of a sector with a central angle of pi/3 radians and a diameter of 12.4m

see explanation

Step-by-step explanation:

The area (A) of the sector of a circle is

A = area of circle × fraction of circle

   = πr² ×

diameter = 12.4 ⇒ r = 6.2, thus

A = π × 6.2² ×

   = π × 38.44 ×

  = ≈ 20.13 m² ( to 2 dec. places )

if x = 1, then the answer is 3.5

according to egenuity the answer is
