Step-by-step explanation:
(1)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
A = 3.14 × 14.5² = 3.14 × 210.25 ≈ 660.185 in²
----------------------------------------------------------------
(2)
The area (A) of the figure is calculated as
A = area of rectangle + area of circle
= (6 × 4 ) + 3.14 × 2² ( d = 4, then r = 2 )
= 24 + 12.56
≈ 36.56 cm²
---------------------------------------------------------------
(3)
The area (A) of the circular lid is
A = πr² ( d = 4, so r = 2 )
= 3.14 × 4
≈ 12.56 in²
does not exsist since the radical cannot be used on a negative number
