The equation to find the interior angles of a regular polygon is S = (n - 2)*180/n, so you do 16-2=14, then multiply 14 by 180 to get 2520. You then divide that by 16 to get 157.5.
Answer:
3,6
Step-by-step explanation:
yes you are right, density formula is :
density = mass ÷ vol
The formula for the surface area of a sphere is 4πr^2
This can be used in the following way, getting the diameter at 18.3:
18.3/2 = 9.15
Saying PI is 3.14 you can do this:
SA = 4*3.14*9.15^2 = 1051.6 m^2
Formula for volume is:
(4/3)πr^3
V = (4/3)*3.14*9.15^3 = 3207.2 m^3
