Geometry review.
I need help with these questions. I don't remember how to do them. I answered question 16 already, I just need help with 12-15 and 17-20.
12. How does the sum of the exterior angles of a square compare to the sum of the exterior angles of a pentagon?
Use the image below to answer questions 13 and 14.
13. If the shape in the center of the image is a regular polygon, what is the measure of EACH interior angle?
14. What is the value of x in the image above?
15. What is the length of the line segment with endpoints ?
16. A right circular cylinder has a base diameter of 12 meters and a height of 16 meters. What is the approximate total lateral surface area of the cylinder?
A= 829.4 m^2
17. The volume of a cone is 218 cubic centimeters and the height of the cone is 13 centimeters. What is the radius of the cone to the nearest whole number?
18. In the diagram shown, a 12-foot slide is attached to a swing set. The slide makes a angle with the swing set. What is the height of the top of the slide (as close as you can get)?
19. A regular hexagon is inscribed in a circle with a radius of 10 meters. What is the length of each side of the hexagon?
20. Calculate the area of the shaded region in the figure shown.

What image?
In mathematics, you don't understand things. You just get used to them.

Re: Geometry review.
Lateral surface area of a cylinder means only the curved area. It does not include top and bottom flat areas. So the answer must be 603 m^2.

Re: Geometry review.
would 13 be:
(n-2)180
(6-2)180
(4)180
720
would 14 be:
720/6
120

Re: Geometry review.
For 13) do they mean the hexagon in the middle?

13) 120 degrees. Your answer looks like the sum of all the angles.

Re: Geometry review.
14. What is the value of x in the image above?
14) If x is the angle then I am getting 60 degrees.

So is not x the supplementary angle of 120 degrees?

Re: Geometry review.
15. What is the length of the line segment with endpoints ?
I have no idea what the question is asking?! Do you?
Have to leave for a bit, see you later.
