Find the volume of a right circular cone that has a height of 12.2 cm and a base with a circumference of 18.5 cm. Round your ans

grin007 [14]

We have been given that a right circular cone has a height of 12.2 cm and a base with a circumference of 18.5 cm. We are asked to find the volume of the cone to nearest tenth.

We know that circumference of circle is equal to $2\pi r$ .

$2\pi r=18.5$

$r=\frac{18.5}{2\pi}$

$r=2.944366$

Now we will use volume of the cone formula to solve our given problem.

$V=\frac{1}{3}\pi r^2 h$

$V=\frac{1}{3}\pi (2.944366)^2\cdot (12.2)$

$V=\frac{1}{3}\pi (8.669291141956)\cdot (12.2)$

$V=\frac{1}{3}\pi (105.7653519318632)$

$V=\frac{1}{3}(332.2716526334804752)$

$V=110.7572175$

Upon rounding to nearest tenth, we will get:

$V\approx 110.8$

Therefore, the volume of the given cube would be approximately 110.8 cubic centimeter.

How do you know if a table is proportional

alexgriva [62]

Answer:

To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.

The graph of an equation with zero slope is a

boyakko [2]

Answer:

Horizontal line

Step-by-step explanation:

Zero slope means that the quotient "rise/run" equals zero.

A zero for a quotient of two numbers implies that the NUMERATOR is zero and the denominator different from zero.

Analyzing what a "rise" of zero means, we understand that there is NO RISE in the graph of the line. And no rise of any type means the line is flat (horizontal).
