Answer:

The total surface area of the given cone is

$S = 4( \sqrt{3}+1)\pi cm^2$

Step-by-step explanation:

<u>Step 1</u>:-

<u>Formula:-</u>

The total surface area of cone is

$S.A = \pi r l +B$

$S.A = \pi r l +area of base$

$S.A = \pi r l+ \pi r^2$ ........(1)

<u>Step 2:-</u>

Given slant height $l = 2\sqrt{3} cm$

and radius of the circle (base) = 2

substituting these values in equation (1)

$S.A = \pi (2)(2\sqrt{3} ) + \pi (4)$

on simplification, we get

$S.A = \pi (4\sqrt{3}+4)$

<u>Final answer</u> :-

$S.A = 4 (\sqrt{3}+1)\pi cm^2$

Drupady [299]

Answer:

x=12

Step-by-step explanation:

since they are similar triangle .Use these ratios

9/6=x+9/14

do cross multiplication

6(x+9)=14*9

6x+54=126

6x=126-54

x=72/6

x=12
