PLEASE HELP ME !!!The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the
cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?
base area for cone= B
base area for pyramid= B, 3r heigh
A. V = pi r³
B. V = 1/3 pi r²
C. V = 2 pi r²
D. V = 1/9 pi r³
E. V = 3 pi r³

The expression for the volume of the pyramid in terms of the radius r of the cone is . So, option A is correct.
The cone is a three-dimensional figure with a vertex and a flat base.
The volume of a pyramid is given by the formula:
Given that:
The base area of the pyramid = B
The height is 3r
The base area of the pyramid is the same as that of the cone.
The base of the cone =
The volume of the pyramid is calculated as:
V =
Therefore, the volume of the pyramid is . So, option A is correct.

Final answer:
The area of a shape can be calculated by multiplying its dimensions. Given a rectangle with length 0.6238 cm and width 6.6 cm, you would multiply these figures to get an area of 4.1 cm².
Explanation:
To calculate the area of a shape in square centimeters, you need to know the dimensions of the shape. For example, if you have a rectangle, you would multiply its length by its width to get the area. If the length was 0.6238 cm and the width was 6.6 cm, the area would be 0.6238 cm x 6.6 cm = 4.11708 cm². However, we often round to two significant figures, so the area would be 4.1 cm². Remember that area is expressed in square units, so for centimeters, the area would be in square centimeters.

891 cm³ convert to milliliters or ml.
1 cubic cm is equal to 1 ml.
891 cm³ * 1 ml/cm³ = 891 * 1ml = 891 ml.
Since, cm³ is found in both numerator and denominator, they cancel each other out leaving ml as the remaining unit.

Let w = amt of water required to make a 10% solution
:
.14(18) = .10(w+18)
2.52 = .1w + 1.8
2.52 - 1.8 = .1w
.72 = .1w
multiply both sides by 10
7.2 = w
:
7.2 liters of water added
