I'm going to have to say C.
The answer is 41.25
hope this helps
Answer:
C = 25 mF
Step-by-step explanation:
Given that,
Two capacitors with capacitances 10mF and 15mF are connected in parallel.
We need to find the total capacitance of the capacitors.
For a parallel combination, the equivalent capacitance is given by :

Substituting the values,

So, the total capacitance of the combination of capacitors is 25 mF.
Given the radius of the inscribed circle, the length of any side of the octagon (and any other polygon) is given by;
Side = 2r* tan (180/n) where r=radius and n=number of sides.
For octagon, n= 8 and radius is given by , r= 7/2 = 3.5 ft
Therefore,
Side = 2*3.5*tan (180/8) 2.8995 ft =2.9 ft.
The correct answer is A.
