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:
![\sqrt{x}](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%7D%20)
Step-by-step explanation:
![\dfrac{1}{x^\frac{-3}{6}} =](https://tex.z-dn.net/?f=%20%5Cdfrac%7B1%7D%7Bx%5E%5Cfrac%7B-3%7D%7B6%7D%7D%20%3D%20)
Reduce the exponent of x.
![= \dfrac{1}{x^\frac{-1}{2}}](https://tex.z-dn.net/?f=%20%3D%20%5Cdfrac%7B1%7D%7Bx%5E%5Cfrac%7B-1%7D%7B2%7D%7D%20)
Use the negative exponent rule: ![a^{-n} = \dfrac{1}{a^n}](https://tex.z-dn.net/?f=%20a%5E%7B-n%7D%20%3D%20%5Cdfrac%7B1%7D%7Ba%5En%7D%20)
![= x^\frac{1}{2}](https://tex.z-dn.net/?f=%20%3D%20x%5E%5Cfrac%7B1%7D%7B2%7D%20)
Use the rational exponent rule: ![a^\frac{m}{n} = \sqrt[n]{a^m}](https://tex.z-dn.net/?f=%20a%5E%5Cfrac%7Bm%7D%7Bn%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%5Em%7D%20)
![= \sqrt{x}](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%7Bx%7D%20)
