Use the formula z=a+bi=|z|(cosθ+isinθ), with |z|=√(a²+b²), and tanθ=b/a<span>
in this case, a=0, b=-3 so </span>|z|=√0²+(-3)²)=3
tanθ=
, notice the denominator is 0, undefined, so the value of θ=π/2
Substitute the values of <span>θ=π/2</span> and <span>|z|=3</span>. into the formula, you'll get <span>3(cos(</span>
)+isin(
))
Circumference c=2(pie)r

C=31.42
Answer:
21 cent per card
Step-by-step explanation:
5.25 / 25 = .21
because 25 can be divided into the first 2 numbers
1 in equals 25.4mm exactly so
.25in(25.4mm/in)=6.35mm
