Answer:
Yes, the answer would be 523.6
Step-by-step explanation:
Formula for Volume of a cone:
V = πr²(h/3)
r = d/2
10/2
r = 5
V = πr²(h/3)
V = π(5²)(20/3)
V = π(25)(20/3)
V = 523.6
Answer:
The area is 35
The perimeter is 24
Step-by-step explanation:
You can count the individual units of the length and the width of the rectangle.
The width is 5, the length is 7

The perimeter is 5+5+7+7=24
Answer:
The complex number has Cartesian form
.
Step-by-step explanation:
First, we need to recall the definition of when is a complex number:
.
Then,
. (I)
Now, recall the definition of the complex exponential:
.
So,
(we use that .
Thus,
Now we group conveniently in the above expression:
.
Now, substituting this equality in (I) we get
.
Thus,
.
Is there more information? You have to do a (48+18) to do this.
a is a variable which is any number.
7.1, or 7 if you have to round it
