A sphere with a radius of 4.8 centimeters is carved out of a right cone with a base radius of 8 centimeters and a height of 15 c

emmainna [20.7K]

Volume of the cone = 1/3 pi r^2 h = 1005.31 cm^3

Volume of the sphere = 4/3 pi r^3 = 463.25 cm^3

Volume of remaining portion of the cone = 1005.31 - 463.25

= 542.1 cm^3 to nearest tenth

Answer:

x = 3.873 units

or x = $\sqrt{15}$ units

Step-by-step explanation:

Hypotenuse = 4 , x = height of this isosceles triangle.

base is 2,

so Use Pythagorean Theorem.

x^2 + 1^2 = 4^2

x^2 = 4^2 - 1^2

x^2 = 16 - 1 = 15

x = root(15) =

If the volume is 1,774 2/3PIcm squared what is the radius of the sphere

Romashka [77]

Answer:

The radius of the sphere is 9.6 cm

Step-by-step explanation:

Given:

The volume of the sphere = $1774 \frac{2}{3} \pi$

To Find:

The radius of the sphere = ?

Solution:

We know that the volume of the sphere is

$V=\frac{4}{3}\pi r^3$

where

r is the radius

Now we have the volume of the sphere

$1774 \frac{2}{3} \pi = \frac{4}{3}\pi r^3$

$1774 (\frac{2}{3}) = \frac{4}{3} r^3$

$1774 (\frac{2}{3})(\frac{3}{4}) = r^3$

$1774 (\frac{2}{4}) = r^3$

$1774 (\frac{1}{2}) = r^3$

$(\frac{1774}{2}) = r^3$

$887 = r^3$

r = 9.6
