Answer:

Step-by-step explanation:
The formula of a lateral area of a cone:

r - radius
l - slant height
The formula of a surface area of a cone:

We have r= 8in and l = 21in. Substitute:


Subtract 18d from both sides
subtract 9k from both sides
simplify 5k + 10 - 18d - 9k to -4k + 10 - 18d
factor out the common term 2
divide both sides by 2
cancel 2 and now simplify brackets
Answer: D) m < -2k + 5 - 9d or the fourth option.
Step-by-step explanation:
then u times the d and e to get the equivalent fraction to the number u get
Let n = the number of points
(x-1) + ... (x-x)
The last term will always be 0, when you reach that, stop.
ex. 1pt: 1-1=0
2pt: (2-1) + (2-2) = 1
3pt: (3-1) + (3-2) + (3-3) = 3
Answer:
x = 27.57 in to the nearest hundredth.
Step-by-step explanation:
The longer diagonal is opposite the obtuse angle.
Also as it is a rhombus all sides = 14 in.
Use the Cosine Rule:
x^2 = 14^2 + 14^2 - 2*14^2 cos 160
x^2 = 760.36
x = sqrt 760.36
x = 27.57 in.
