The third answer is correct, i am one of the best in my class take my word for it.
The formula for finding the interior angle sum of any polygon is (n - 2) x 180 where n is the number of sides, so...
(22 - 2) x 180 = 20 x 180 = 3,600 so the interior angles of a 22 sided polygon sum to 3,600 degrees.
Hope this helps :)
Finding the radius from it's surface area, the volume of the sphere is of 268.08 cm³.
<h3>What are the surface area and the volume of an sphere?</h3>
For an sphere of radius r, we have that the surface area is given by:

The volume is given by:

Considering the surface area of 200.96 cm², the radius is given by:



r = 4 cm
Hence the volume is given by:

Answer: 3(x+4)=x+18
Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.
