1. The surface area of a cone S is S= $\pi r^{2}+ \pi rl$ , where r is the radius of the base and l is the slant height.

2. The slant height l is found as follows:

$l^{2}= OC^{2}+ OB^{2}$
$l^{2}= 12^{2}+ 62^{2}=144+3844=3988$

$l= \sqrt{3988}=63.15$

3.

$A=\pi r^{2}+ \pi rl=3.14(12)^{2}+3.14*12*63.15
$
$= 452.16+2379.492 =2831.652 ( m^{2} )$

$= 452.16+2379.492 =2831.652 ( m^{2} )$

4. The answer is C

Answer:

No solution

Step-by-step explanation:

5(x + 4) – x = 4(x + 5) – 1

x = ?

Solution:

5(x+4)−x=4(x+5)−1

Apply Distributive property:

(5)(x)+(5)(4)−x=(4)(x)+(4)(5)−1
5x+20−x=4x+20−1

Combine Like Terms:

(5x−x)+(20)=(4x)+(20−1)
4x+20=4x+19
4x+20=4x+19

Subtract 4x from both sides:

4x+20−4x=4x+19−4x
20=19

Subtract 20 from both sides:

20−20=19−20
0=−1

There isn't any solutions.
