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.

I have a Math Quiz for You Mathmatizers !!! I have a 72" 2x4 with 2 cuts/3 pieces The 2nd piece is twice as long as the 1st piec

olya-2409 [2.1K]

Answer:

the answer is 4

Step-by-step explanation:

let x= length of the first piece.

second piece is 2x, right

third piece x+5, right

Total, in x-talk, is x + 2x + x+5 and that equals 21 feet, right.

Combine like terms: 4x + 5 = 21. Still with me?

So 4x = 16 (do you see why?)

So, what x must x be is 4
