Find the volume of the sphere. express your answer in term of Pie​
IceJOKER [234]

Answer:

\large\boxed{36\pi}

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

R - radius

We have R = 3 ?. Substitute

V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=(4)\pi(9)=36\pi

If the radius is 30, then the volume is:

V=\dfrac{4}{3}\pi(30^3)=\dfrac{4}{3}\pi(27,000)=(4)\pi(9,000)=36,000\pi

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.

Therefore the volume:

V=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3,375)=(4)\pi(1,125)=4,500\pi

Sense they both are absolute values, they are pretended to be as normal numbers. By simplifying this, your correct answer would be 11.

Hope this helps.

The equation of the line through point (-5,0) and parallel to the y-axis is
Mrac [35]
It's x=-5. It is a vertical line, and vertical lines have a consistent x coordinate. Since it passes through (-5,0), you take the x-coordinate of this point.
