Answer:

Step-by-step explanation:
Given that,
Radius of a cone, r = 13 cm
Slant height of the cone, l = 20 cm
We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

Put all the values,

So, the surface area of the cone is
.
Answer:
x = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3x−2)=8(2x+3)
(4)(3x)+(4)(−2)=(8)(2x)+(8)(3)(Distribute)
12x+−8=16x+24
12x−8=16x+24
Step 2: Subtract 16x from both sides.
12x−8−16x=16x+24−16x
−4x−8=24
Step 3: Add 8 to both sides.
−4x−8+8=24+8
−4x=32
Step 4: Divide both sides by -4.
−4x
−4
=
32
−4
x=−8
Answer:
x=−8
Your basically just adding 9 so 4 plus 9 is 13 and 13 plus 9 is 22
