Answer:
8 is the radius.
Step-by-step explanation:
The standard form of a circle is 
.
However, I like to call it center-radius form because it tells us the center and the radius.
The center is 
and the radius is 
.
So your equation is 
.
So the center for this circle is (0,0) and the radius is 8.
If it wasn't so obvious that 
is 64 then you could have entered 
in your calculator to get 8.
Answer:6
Step-by-step explanation:
The answer is 21.2 ft²
To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² h
We have:π = 3.14r = 1.5 fth = 3 ft
Therefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
here you go
