You have a cone with base diameter of 12 cm. and a height of 8cm. (Part 1) If the cone has its tip pointing downward and water is poured into the cone up to a height of 7cm, what percent of the cone is filled with water?

(Part 2) If the cone’s base is sealed so water cannot leak out and then the cone is flipped so that its tip is pointing upward, then what will the height of the water be?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
