The volume of a cylinder is denoted by the formula: , where r is the radius and h is the height.
Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.
The exponential formula for this situtation will be given by: f(x)=ae^(-bx) where: a=initial price b=rate x=time in years hence the formula will be: f(x)=28750e^(-0.12x) thus the value of the car in 2018 will be: x=2018-2012=6 years thus f(6)=28750e^(-0.12*6) f(6)=$13,994.13
