Answer:

So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880

Step-by-step explanation:

In this question we have been given the sum of interior angles of a polygon which is 2880, having n sides. We have to find n i.e the no of sides of polygon.

The formula used is S= (n-2) *180

where S= sum of interior angles

and n= no of sides

putting value of S and finding n,

2880 = (n-2) *180

2880/180 = (n-2)

16 = n-2

=> n= 16 +2

=> n= 18

So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880

the surface area of a sphere is 1,017.36 square inches.what is the volume of the sphere? use 3.14 for pi

Answer:

Area = 254.34 inches ³

Step-by-step explanation:

The formula to find the surface area of a sphere is:

$SA = 4\pi r^{2}$

To find the volume of the sphere, we first need to figure out the radius ( $r$ ) of the sphere. We can accomplish this by reversing the formula that was used to find the surface area. $(1017.36 in^{2})$
