Answer:

Step-by-step explanation:

diameter = 12 cm

r = 12 ÷ 2 = 6 cm

h = 6 cm

$\sf \boxed{\text{\bf Volume of cone = $\dfrac{1}{3} \pi r^2h$ }}$

$\sf = \dfrac{1}{3}*3.14*6*6*6\\\\ = 226.08 \ cm^3$

To find the surface area, we need to find the slant 'l'

$\sf l = \sqrt{h^2+r^2}\\\\ =\sqrt{6^2+6^2}\\\\ = \sqrt{36+36}\\\\ =\sqrt{72}\\\\= 8.49 \ cm$

$\sf \boxed{\text{\bf Total surface area of cone = $\pi r(r+l)$}}$

= 3.14 * 6 * (6 + 8.49)

= 3.14 * 6 * 14.49

= 273 cm²

Can somebody help with these three questions plz

liraira [26]

$\bf \sqrt{2}\left(3\sqrt{2}+\sqrt{18} \right)~~
\begin{cases}
18=2\cdot 3\cdot 3\\
\qquad 2\cdot 3^2
\end{cases}\implies \sqrt{2}\left(3\sqrt{2}+\sqrt{2\cdot 3^2} \right)
\\\\\\
\sqrt{2}\left(3\sqrt{2}+3\sqrt{2} \right)\implies \sqrt{2}\left(6\sqrt{2} \right)\implies 6\left(\sqrt{2}\right)^2\implies 6\cdot 2\implies \stackrel{rational}{12}$
