43 pF = 0.000043 microF
using the equation C=(k*epilison*Area)/separation
where,
epsilon = 8.854*10^12 F/m
C= 43 pF
A=0.28
k=1.0
solve for d (separation)
d=5.765 cm
b)
C = (8.2*0.28*8.854*10^12)/(0.05765)
C = 3.525*10^10 F = 352.5 pF

From Cynthia: C = 1.6 pF = (epsilon*Area*k)/d rearranging, d...

C = 1.6 pF = (epsilon*Area*k)/d rearranging, d = (epsilon*Area*k)/1.6pF where, k=1.0 epsilon = 8.854*10^12 F/m area = unknown doubling the separation, d = (2*area*1.0*8.854*10^12)/(1.6*10^12) d = 11.0675Area Now that d will be plugged into the new equation 2.8 pF = (k*area*epsilon)/d 2.8 pF = (k*area*epsilon)/(11.0675Area) areas cancel out, and you solve for k k = 3.5

RE:
A parallelplate airfilled capacitor has a capacitance of 43 pF.?
A parallelplate airfilled capacitor has a capacitance of 43 pF. (a) If each of its plates has an area of 0.28 m2, what is the separation? (b) If the region between the plates is now filled with material having κ = 8.2, what is the capacitance?
