221.56, because in order to get the area of a circle, you must use this formula: area = (pi divided by 4) x diameter squared.
In this case, area = (3.14 / 4) x (16.8 x 16.8)
1.)
x + (x + 1) = 145
2x + 1 = 145
2x = 145 - 1
2x = 144
x = 72
if x is equal to 72
72 + 1 = 73
therefore the 2 integers is 72 and 73
2.
x + (x + 1) + (x + 2) = 54
3x + 3 = 54
3x = 54 - 3
3x = 51
x = 17
numbers are, 17, 18 and 19
