Answer:
Option C.
Step-by-step explanation:
Note : In the given points one point is (8,-2) instead of (-6,-2).
The standard form of a circle is
where, (h,k) is center of circle and r is radius.
It is given that center of the circle is (-1,-2). So,
...(1)
It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).
Substitute x=6 and y=-2 in equation (1).
Substitute
in equation (1).
Therefore, the correct option is C.

Answer:
V = 77 m^3
Step-by-step explanation:
We want the volume of the cylinder
V = pi r^2 h
We know the diameter not the radius
r = d/2 = 7/2 = 3.5
V = 3.14 * (3.5)^2 (2)
V = 76.93 m^3
To the nearest cubic meter
V = 77 m^3

Volume of the sphere = 4/3 πr³
Volume of the sphere = 4/3 π (6)³
Volume of the sphere = 904.78 ft³ (nearest hundredth)
1 minute = 23 ft³
Find number of minutes :
904.78 ÷ 23 = 40 mins (nearest minutes)
