IceJOKER [234]

Answer:

113.04 cm squared

Step-by-step explanation:

the area of a circle is:

A=πr2

so as you written before the pi must be 3.14

and the radius is the diameter/2(12/2=6)

A= 3.14 x 6 x 6

A= 113.04 cm squared

How do I find the surface area of a right circular cone?

UkoKoshka [18]

Greetings!

"<span>How do I find the surface area of a right circular cone?"...
</span>
The formula to find the surface area of a right cone is :
$=\pi r(r+ \sqrt h^2+r^2)$

Lets it out:
$r=5$ and $h=12$

$=\pi(5)((5)+ \sqrt (12)^2+(5)^2)$
Follow PEDMAS.
$=\pi(5)((5)+ \sqrt 169)$
$=\pi(5)((5)+ 13)$
$=\pi(5)(18)$
$=15.7079633(18)$
$=282.743339$

The SA of the cone would be <span>282.743339.

Hope this helps.
