Answer:

756π cm^3.

Step-by-step explanation:

Volume of the cone

270π = 1/3 π r^2 h

270π = 1/3 π r^2 * 10

r^2 = 270 / ( 10/3 )

r^2 = 81

r = 9 cm.

So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3

= 486π cm^3.

So the volume of the whole solid = 270π + 486π

= 756 π cm^3.

Find x in the given figures.

Answer:

$\large\boxed{X=\sqrt{12}\ in=2\sqrt3\ in}$

Step-by-step explanation:

ΔADC and ΔCBD are similar. Therefore the corresponding sides are in proportion:

$\dfrac{AD}{CD}=\dfrac{CD}{DB}$

We have

AD = 2, CD = X, DB = 6.

Substitute:

$\dfrac{2}{X}=\dfrac{X}{6}$ <em>cross multiply</em>

$X^2=(2)(6)\\\\X^2=12\to X+\sqrt{12}$

$\sqrt{12}=\sqrt{4\cdot3}=\sqrt4\cdot\sqrt3=2\sqrt3$
