Answer:


Step-by-step explanation:
Figure of cone is missing. See attachment
Given
Radius, R = 2m
Let L = KL=LM=KM
Required:
Volume, V and Surface Area, A
<u><em>Calculating Volume</em></u>
Volume is calculated using the following formula

Where R is the radius of the cone and H is the height
First, we need to determine the height of the cone
The height is represented by length OL
It is given that KL=LM=KM in triangle KLM
This means that this triangle is an equilateral triangle
where OM = OK = 
OK = 
Applying pythagoras theorem in triangle LOM,
|LM|² = |OL|² + |OM|²
By substitution
L² = H² + (
)²
H² = L² -
²
H² = L² (1 -
)
H² = L² 
H² = 
Take square root of bot sides


Recall that 




in terms of
an d L where L = KL = LM = KM
<u><em>Calculating Surface Area</em></u>
Surface Area is calculated using the following formula

Divide 1/2 by 4 and you get 0.125
Answer:
12 pens
Step-by-step explanation:
Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.
Price of a notebook = $1.59
Price a pen = $0.29
Total amount spent = $5.07
But,
1.59 + 0.29 n = 5.07
So that,
0.29 n = 5.07 - 1.59
0.29 n = 3.48
n = 
= 12
Therefore, Kamila bought 12 pens.
The correct answer is: [D]: "5 (five)" .

<u>Note</u>: The term of "degree 8" is the term with a variable with
an exponent of "8" ; which in this case is " + 5x⁸ ".
The "coefficient" is "5" (five).
