Mia spent 50*$28 = $1,400
From batch 1, she earned $1,862
From batch 2, she earned $480
In total, her net earnings are $942
Net Profit Margin: 40.22%
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
