Find the volume of a right circular cone that has a height of 4.1 cm and a base with a diameter of 14.8 cm. Round your answer to

podryga [215]

Answer:

$V=235.1\ cm^3$

Step-by-step explanation:

<u>Volume of a Cone</u>

The volume of a right circular cone with height h and a base radius r is:

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

The height of the given cone is h=4.1 cm and its diameter is d=14.8 cm. Since the radius is half the diameter, r=7.4 cm.

Calculate the volume:

$\displaystyle V=\frac{1}{3}\pi\cdot 7.4^2\cdot 4.1$

$\displaystyle V=\frac{1}{3}\pi\cdot 54.76\cdot 4.1$

$\displaystyle V=\frac{1}{3}\pi\cdot 224.516$

$\boxed{V=235.1\ cm^3}$

The local school sponsored a mini-marathon and supplied 84 gallons of water per hour for the runners. What is the amount of wate

Dmitrij [34]

All you need to do is multiply 84 by 4.

The number of gallons by the number of quarts <em>in a gallon. </em>

80*4= 320

4*4=16

320+16= 336

There are 336 quarts of water supplied an hour.

I hope this helps!

The path of a model rocket can be represented by the equation h(t)=-t2+15t+16, where h(t) is the height, in feet, of the rocket

Musya8 [376]

The height is 52 feet.

Using t=3, we have:
-3² + 15(3) + 16 = -9 + 45 + 16 = 52
