Answer:
The area of the cone is "1,695.6 cm³".
Step-by-step explanation:
The given values are:
Diameter of cone,
d = 18 cm
then,
Radius,
r = 
= 
= 
Height,
h = 20 cm
As we know,
⇒ Area of a cone = 
On substituting the given values in the above formula, we get
⇒ = 
⇒ = 
⇒ = 
⇒ = 
Answer:
11=x
Step-by-step explanation:
1) distribute the "2"
2x+14=36
2) subtract 14 on both sides
2x+14=36-14
2x=22
3) divide by 2 on both sides
2x/2=22/2
x=11

Answer:
Inverse property of addition.
Answer:
x = 15
Step-by-step explanation:
-3x+20+7x=80
Combine like terms
4x+20 = 80
Subtract 20 from each side
4x+20 -20 = 80-20
4x = 60
Divide by 4
4x/4 = 60/4
x = 15
The area is 279. You do 11×19 to get the bottom portion. That will give you 209. Then for the top subtract 11 from 18 to get that side length and then do 7×10. With that you will get 70 and then you add 209 to that. 209+70=279.
