Answer:
Option C 
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The distance from the center of the circle to any point on the circumference of the circle is equal to the radius of the circle
we have
(1,-1) and (5,7)
the formula to calculate the distance between two points is equal to

substitute the values



step 2
Find the equation of the circle in center radius form

where
(h,k) is the center
r is the radius
substitute


Answer:
24
Step-by-step explanation:
Divide 40 by 10 and multiply your answer by 6
Volume = pi x radius^2 x height
400=3.14 x 4^2xheight
400=50.24h
400/50.24= h
7.96 = height
