radius = (4*10^2 + 24^2)/8*10 =
(400 + 576)/80=
976/80 = 12.2
diameter = 12.2 x 2 = 24.4

The dealers cost of the refrigerator is $591.36
<h3>How to determine the dealer cost</h3>
Represent the dealer cost of the refrigerator with x.

x = 591.36
Hence, the dealers cost of the refrigerator is $591.36
