What is the approximate volume of a cone with a radius of 15 cm and a height of 4 cm? Round your answer to the nearest hundredth

vichka [17]

Answer:

Volume of a cone $=942.86cm^3$

Step-by-step explanation:

Given that the radius of a cone is 15cm and its height is 4cm

That is r=15cm and h=4cm

To find the volume of a cone :

volume of a cone $=\frac{\pi r^2h}{3}$ cubic units

Now substitute the values in the formula we get

volume of a cone $=\frac{(\frac{22}{7}) (15)^2(4)}{3}$

$=\frac{(\frac{22}{7}) (225)(4)}{3}$

$=\frac{19800}{21}$

$=942.857$

Now round to nearest hundredth

$=942.86$

Therefore Volume of a cone $=942.86cm^3$

Solve the equation using square roots.

Virty [35]

Answer: LAST OPTION.

Step-by-step explanation:

1. You have the following equation:

$6x^{2}=54$

2. Then you must solve for x, as following:

$x^{2}=54/6\\x^{2}=9\\x=\sqrt{9}\\x=+/-3$

Therefore, as you can see above, the answer for the exercise is the last option.

PLEASE HELP!!! WILL GIVE BRAINLIEST!!!!!

castortr0y [4]

Answer:

y = -1|x+1| +1

Step-by-step explanation:

The vertex form of an absolute value equation is y = a* |x-h| +k

a = -1 because it opens downwards with a slope of ± 1. Next it's vertex is at (-1,1). So replace h with -1 and k with one.

y = -1|x+1|+1
