Emmanuel carves a cone-shaped hollow out of a solid clay cylinder. What is the approximate volume of the solid portion of the cy

bixtya [17]

Answer:

$3.14r^2(h-\frac{1}{3}h_1)$

Step-by-step explanation:

Let h be the cylinders height and r the radius.

-The volume of a cylinder is calculated as:

$V=\pi r^2h$

-Since the cone is within the cylinder, it has the same radius as the cylinder.

-Let $h_1$ be the height of the cone.

-The area of a cone is calculated as;

$V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi r^2h_1$

The volume of the solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:

$V=V_{cy}-V_{co}\\\\=\pi r^2h-\frac{1}{3}\pi r^2 h_1, \pi=3.14\\\\=3.14r^2(h-\frac{1}{3}h_1)$

Hence, the approximate area of the solid portion is $3.14r^2(h-\frac{1}{3}h_1)$

jenyasd209 [6]

Move the 11x to the left and the +54 to the right. Their signs will flip:

14x-11x = 96-54
3x = 42
x = 14

318.9 in scintific notation

ivanzaharov [21]

Scientific notatino is
(number that is greater than or equal to 1 and less than 10) times (10^x)

so
318.9
we need to make it less than 10
move decimal 2 places to left
3.189

to make it the same number, we multipl it by 10^2 to make it go back

scientific is
3.189 times 10^2
