None of the options are correct
О E. 289.2 cm
Volume of a cylinder = v = л r² h
л = 3.1416 (aprox)
r = radius
h = height
8177 = 3.1416 * 3² * h
8177 = 3.1416 * 9 * h
8177 = 28.2744 * h
8177/282744 = h
h = 289.2 cm
3/4 (A)
replace x with -2 in the function
3 · 2^-2 = 3 · 0.25
3 · 0.25 = 0.75
0.75 = 3/4
Population t years after 2000 = 736,000 × 1.0149^t
736,000 × 1.0149^t = 1,000,000
1.0149^t = 1,000,000/736,000 = 125/92
Take log base 1.0149 of both sides
t ≈ 20.7
Population exceeds a million in 2021
