What is the only unknown (variable) needed to find the volume of a sphere?
yuradex [85]

Sphere

The radius of the sphere is the only unknown variable need to find the volume of a sphere.

Step-by-step explanation:

Sphere is a geometrical three dimensional round figure with every point on its surface equidistant from its center. It is a three dimensional representation of a circle. A line which connects from the center to the surface is called radius of the sphere.The diameter of the sphere is the longest straight line which passes through the center of the sphere.

The volume of sphere is given by:

Volume of sphere(V) = \frac{4}{3}\pi r^{3} \\

where V is the volume of the sphere

r is the radius of the sphere

\pi = \frac{22}{7}  = 3.14

Hence the only unknown variable to find the volume of a sphere is the radius.

The sum of the measures of the interior angles of a polygon is 2880°. How many sides does the polygon have?
harina [27]

Let

S------> The sum of the measures of the interior angles of a polygon

n-------> number of sides of a polygon

we know that

The formula to find the sum of the measures of the interior angles of a polygon is equal to

S=(n-2)*180°

in this problem

S=2880°

Solve for n

S=(n-2)*180\\ \\ n=\frac{S}{180}+2\\ \\ n=\frac{2880}{180}+2\\ \\ n=16+2\\ \\ n=18\ sides

therefore

the answer is

18\ sides
