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

Answer:
A
Step-by-step explanation:
We know million has 6 zeros.
So, 1 million would be written as:
1,000,000
Similarly, 27 million would be written as:
27,000,000
We know writing a number in scientific notation would make this a decimal in 1 decimal place, so we would select "2.7" as the base of the scientific number.
Now, how many places to the right do we need to go (in 2.7) to make it 27,000,000?
Counting, we see: 7 places
So, power of 10 would be "7", thus we can write:
Answer choice A is right
