Answer:

r = 10.72 cm

Step-by-step explanation:

h = 6 cm

Volume of cone = 722 cubic cm

\frac{1}{3}\pi r^{2}h=722\\\\\frac{1}{3}*3.14*r^{2}*6=722\\\\r^{2}=\frac{722*3}{3.14*6}\\\\r^{2}=114.97\\\\r = \sqrt{114.97}\\\\r = 10.72

The ratio of their surface areas will be a²/b². And the ratio of their volumes a³/b³.

<h3>What are the surface area and the volume of an object?</h3>

The size is the amount of space covered by a two-dimensional hard surface.

The volume of an element or compound is the sufficient space it takes up, calculated in cubic units.

1.  The ratio of the surface area of similar solids

If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their surface areas will be a²/b².

2.  The ratio of the volume of similar solids

If the ratio of the corresponding edge lengths of two similar solids is a:b, then the ratio of their volumes a³/b³.

More about the surface area and the volume link is given below.

Please help!!!! BRAINLIEST for whoever is correct!! What is the difference of the rational expressions below?
Nostrana [21]

Answer:

<h2>\frac{3x + 25}{5 {x}^{2} }</h2>

Step-by-step explanation:

\frac{x + 5}{ {x}^{2} }  -  \frac{2}{5x}

Write all the numbers above the least common denominator {5x}^{2}

\frac{5(x + 5) - 2x}{5 {x}^{2} }

Distribute 5 through the parentheses

\frac{5x + 25 - 2x}{5 {x}^{2} }

Collect like terms

\frac{3x + 25}{5 {x}^{2} }

Hope this helps...

Good luck on your assignment...
