The answers according to rows are:
- ROW 1 : diameter of base = 10, base area = 25π, volume of cylinder = 175π volume of cone =
π
- ROW 2 : base radius = 3, base area = 9π, height = 40/3, volume of cylinder = 120π
- ROW 3 : base radius = 6, base diameter = 12, height = 4, volume of cylinder = 144π
Mensuration is an aspect of geometry that deals with measurement of volumes and area.
Analysis:
Row 1
Diameter of base = 2 x radius = 2 x 5 = 10
Base area = π = π
= 25
Volume of cylinder = base area x height = 25π x 7 = 175π
Volume of cone = 1/3 x volume of cylinder = 175π/3
Row 2
Base radius = base diameter/2 = 6/2 = 3
Base area = π = π
= 9π
Volume of cone = 1/3 x base area x height
base area x height = 3 x volume of cone
base area x height = 3 x 40π
Height = 120π/9π = 40/3
Cylinder volume = 3 x cone volume = 3 x 40π = 120π
Row 3
Base area = π
36π = π
r2 =
r = 6
Base diameter = 2 x 6 = 12
Volume of cone = 1/3 x base area x height
48π = 1/3 x 36π x height
Height = 4
Cylinder volume = 3 x 48 = 144π
In conclusion,
ROW 1 : diameter of base = 10, base area = 25π, volume of cylinder = 175π
volume of cone = π
ROW 2 : base radius = 3, base area = 9π, height = 40/3, volume of cylinder = 120π
ROW 3 : base radius = 6, base diameter = 12, height = 4, volume of cylinder = 144π

The line g(x) has slope ...
(change in y)/(change in x) = (-18 -(-20))/(1 - 0) = 2
so can be written in slope-intercept form as
g(x) = 2x -20
The x-intercept of this line is at x=10.
0 = 2x -20 . . . . the x-intercept is where g(x) = 0
20 = 2x
10 = x
The circle also intersects the x-axis at x=10, so that will be one point that is shared by the circle and g(x). A graph shows there is also another point of intersection, (6, -8).
Yes, the linear function g(x) will intersect the circle at 2 points with positive x-coordinates.
