If a cone shaped vase can hold 45 cubic centimeter of water and has a radius of 2 centimeters what is the height of the vase use

xz_007 [3.2K]

Answer:

The height of the vase is $h=10.75\ cm$

Step-by-step explanation:

we know that

The volume of a cone is equal to

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

we have

$V=45\ cm^{3}$

$r=2\ cm$

$\pi =3.14$

substitute and solve for h

$45=\frac{1}{3}(3.14)(2)^{2} h$

$135=(3.14)(4)h$

$135=12.56h$

$h=135/12.56$

$h=10.75\ cm$

The area of the bottom of a circular pool 452.2 ft2. What is its circumference, rounded to the nearest tenth?

Alborosie

The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.

To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.

To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.

Finally, round the number you get to the nearest tenth.
