Answer: ≈4.09π in. ≈12.85 in.
Answer:

Step-by-step explanation:
we are given different angles
we can see that each angles have different denominators
so, firstly we will find common denominators
denominators are 1 , 2,3,4,6
so, LCD will be 12
now, we will make denominator of all terms 12








we can see that denominators are same
so, we can arrange it according to numerators as

we can replace values
and we get order as

Answer:
-8i
Step-by-step explanation:
To multiply numbers is polar form
z1 = r1 ( cos theta 1 + i sin theta 1)
z2 = r2 ( cos theta 2 + i sin theta 2)
z1*z2 = r1*r2 (cos (theta1+theta2) + i sin (theta1+theta2)
z1 = 2(cos 70° + i sin 70°)
z2 = 4(cos 200+ i sin 200)
z1z2 = 2*4 (cos (70+200) + i sin (70+200)
z1z2 = 8 (cos(270) + i sin (270))
= 8 (0 + i (-1))
=-8i
