Answer:
<h2>
6cis120°</h2>
Step-by-step explanation:
The general form of a complex number z = x+iy
If x = rcos
and y = rsin
where r is the modulus of the complex number and is the argument, z in polar form is represented as:
z = rcos+ rsin
z = r(cos+ isin)
z = rcis
Given the complex number z=−3+3√3i
r = 
since the argument is negative and tan is negative in the 2nd and 4th quadrant,
In the second quadrant, theta = 180- 60 = 120°
On substituting r and theta, the complex number in polar form is expressed as 6cis120°

The volume of a vase with a radius of 1 m and height of 7 m is 22000 L
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Cylinder is solid geometrical figure with straight parallel sides and a circular or oval cross section
Let us assume that the vase has a base with radius of 1 m and height of 7 m, hence:
Volume of vase = π * radius² * height
Volume of vase = π * (1)² * 7 = 22 m³ = 22000 L
The volume of a vase with a radius of 1 m and height of 7 m is 22000 L
