Math help please 10 points?
4. What is the measure of S?
14. When the point (-4, 12) is dilated with the center of dilation at the origin, then the image of the point is (-1, 3). What is the scale factor of this dilation?
11. A right cone has a base diameter that is 8 cm and a slant height that is 37 cm. What is the surface area of the cone?
answer to the 2nd question (14 - ) is 0.25
as the points ( -4, 12 ) is multiplied by 1/4 which is 0.25
answer to the 3rd question ( 11. ) answer is 465
as the s.a area of the cone is derived from the equation s.a = pie * radius ( 4) by slant height ( 37)
i think there is something missing in your question can you please check it
answer to the 1st question ( 4) answer is 22 degrees
youtube offers videos on math home work. teachers for each math section you have.
I hope it helped at least a little....
I hated geometry so i never learned it really well so i wasnt sure about the second two and i didnt want to give you a wrong answer...im sorry...
My workings make it as:
4. 42 Degrees
11. Volume of a cone is deffinatley V = 3.14 X R^2 X h / 3
So, Volume = 360
