Answer:

The total surface area of the given cone is

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

Step-by-step explanation:

Step 1:-

Formula:-

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)

Step 2:-

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

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

Final answer :-

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

kupik [55]

Hey there :)

5 quarts of oil and an oil filter - $20.35
With couple - $4.43 less
Final cost?

We subtract 4.43 from $20.35
Why? That's the expected amount [ without a coupon ]

20.35
- 4.43
15.92

The final cost will be $15.92
