Answer:

Step-by-step explanation:
the arc length is equal to the radius x angle (in radians)

s= arc length, r= radius and a= the angle
solve for a ; a= s/r; a=

The volume is nine wholes and 3/4 or 9 3/4
Answer:

Step-by-step explanation:
You can use these Cramer's formulas to solve for x and y:

where

So,

A=Annual amount=2000
i=annual interest=0.0205
n=number of years=3
Present value
=A((1+i)^n-1)/(i(1+i)^n)
=2000(1.0205^3-1)/(.0205(1.0205^3))
=5762.15
Given:
Rectangular coordinate = (8, 6)
To convert:
Rectangular coordinate to polar coordinate with r > 0 and 0 ≤ θ < 2π.
Solution:
Let us find r:



r = 10
Now, find θ:


Cancel the common factor 2.


θ = 36.87°
The polar coordinates are (r, θ) = (10, 36.87°).
