In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s

Multiply the $0.15 by the 30 days then add $2.00 to your total.
The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
Find the area of the triangle, then multiply that by the depth of the prism.
Area of triangle = 1/2 x base x height = 1/2 x 14 x 16 = 112
Volume = 112 x 32= 3584 ft^3
