For this case we have that by definition, the surface area of a cone is given by:
Where:
r: It is the cone radius
s: It's the slant height
According to the data we have:
Substituting:
Thus, the surface area of the cone is
Answer:
Option B
Answer:
My step-by-step explanation:
- <u><em>We would use the formula πr2 (pi x radius x radius) </em></u>
<em> </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>
- <u><em> And so we find: 6mm÷2=3mm </em></u>
3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
- <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>
<u><em /></u>

Hope this helps you!
Answer:
The number of arrangements she made was:
2 small arrangements
3 medium arrangements
4 large arrangements
Step-by-step explanation:
There are 3 sizes of arrangement
Let r = roses
d = daisies
c = chrysanthemums
Each small arrangement contains one rose, four daisies, and four chrysanthemums.
r + 4d + 4c
Each medium arrangement contains two roses, four daisies, and five chrysanthemums.
2r + 4d + 5c
Each large arrangement contains four roses, six daisies, and six chrysanthemums.
4r + 6d + 6c
We are told that
One day, the florist noted that she used a total of 24 roses, 44 daisies, and 47 chrysanthemums in
Rearranging the equations,
Where s = small arrangements
m = medium arrangements
l = large arrangements
we have:
s + 2m + 4l = 24 ........Total number of roses
3s + 4m + 8l = 50 ....... Total number of daisies
3s + 6m + 6l = 48 ......... Total number of Chrysanthemums
From the above:
We can see that we have 3 equations and to solve it, we use Matrix method to solve this question because this is a 3 system (3 × 3) Matrices
I am unable to type the Matrices solution here, so please find it attached to this answer.
The number of arrangements she made was:
2 small arrangements
