17. A #12 wire has a diameter of 80.81 mils. If CM=D squared, the cma would be
(a) 4110 (b) 5630 (c) 4374 (d) 6530


Sagot :

D. 6530 circular mils

Work

Given a wire with a diameter of 80.81 mils, we are asked to find the CMA which is equivalent to D².

Knowing that, we can square the diameter to obtain the CMA.

CMA = D²

D = 80.81

CMA = (80.81)²

CMA = 6530.2561

round to nearest whole number

6530.2561 ---> 6530

Thus, D would be the most fitting option.
