The awnser is D but could also maybe be B
Answer:
15(a)(b)(c)
Step-by-step explanation:
I don't know what your asking for
Their intersection is 7 because is you look at the coordinates of both A and B they have 7 in common
The radii of the frustrum bases is 12
Step-by-step explanation:
In the figure attached below, ABC represents the cone cross-section while the BCDE represents frustum cross-section
As given in the figure radius and height of the cone are 9 and 12 respectively
Similarly, the height of the frustum is 4
Hence the height of the complete cone= 4+12= 16 (height of frustum+ height of cone)
We can see that ΔABC is similar to ΔADE
Using the similarity theorem
AC/AE=BC/DE
Substituting the values
12/16=9/DE
∴ DE= 16*9/12= 12
Hence the radii of the frustum is 12
Answer:
11/9
Step-by-step explanation:
Additive inverse is just another overly-complicated word for opposite. The answer is 11/9.
