Answer:
cost to rent 1 water tank is $923.16
Explanation:
the volume of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
given r = 7 ft and h = 2 ft
substitute these values into the formula for V
V = π × 7² × 2 [ using 3.14 for π ]
V = 3.14 × 49 × 2 = 307.72 ft³
the rental cost is $3 per ft³ then
rental cost = 307.72 × $3 = $923.16
