Given sphereradius and pival, compute the volume of a sphere and assign to spherevolume. use (4.0 / 3.0) to perform floating-point division, instead of (4 / 3) which performs integer division. volume of sphere = (4.0 / 3.0) π r3 (hint: r3 can be computed using *)

The volume of a sphere is

As the hint suggests, we can avoid the use of powers, if we recall that

So, we can rewrite the volume as

Since we're given two variables storing the values of and the radius, we can write the line of code as follows:

spherevolume = (4.0 / 3.0) * pival * sphereradius * sphereradius * sphereradius ;

The program which computes the volume of a sphere written in python 3 goes thus :

spherevolume = (4.0/3.0)*pival*(sphereradius)**3

sphereradius = r

pival = 3.142

The formula for obtaining the volume of a sphere can be expressed thus :

Volume = (4.0/3.0) × πr³

Hence, using Python :

spherevolume = (4.0/3.0)*pival*(sphereradius)**3

print(spherevolume)

# displays the calculated volume of the sphere based on the value of the Radius supplied.

The triangle in the circle is an isosceles triangle as both the lengths are touching the circumference which makes it the same as the radius.

to find x you will have to subtract 75 from 180 and divide the answer by two.

75 + x + x = 180
2x = 105
x = 105/2
x = 52.5°
