The circumference is the diameter times PI
The exact circumference would be 9PI cm
The approximate circumference would be 9 x 3.14 = 28.26 cm
H(t) = -16t^2 +42t = -16t(t -2.625)
The maximum height will be reached at t=1.3125. It will be
h(1.3125) = 16*1.3125^2 ≈ 27.6 Which corresponding to the 4th selection
