Please help im literally crying i cant fail this

densk [106]

Don't cry!! You got this! Just take it one step at a time and list your known values:

h = 5 m

r = 5 m

The volume of a cone is V = (1/3)πr^2h

V = (1/3)(3.14)(5)^2(5) = 130.83 m^3

I believe in you! I hope this helps!

Answer:

$(\sqrt{30}-2\sqrt{5})\ m$

Step-by-step explanation:

we know that

The length of the side, s, of a cube with a surface area, SA is equal to the formula

$s=\sqrt{\frac{SA}{6}}$

Step 1

Find the length of the side, s, of a cube with a surface area of $180\ m^{2}$

we have

$SA=180\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{180}{6}}$

$s=\sqrt{30}\ m$

Step 2

Find the length of the side, s, of a cube with a surface area of $120\ m^{2}$

we have

$SA=120\ m^{2}$

substitute in the formula

$s=\sqrt{\frac{120}{6}}$

$s=\sqrt{20}=2\sqrt{5}\ m$

Step 3

Find the difference of the length sides

$(\sqrt{30}-2\sqrt{5})\ m$
