A) 10 cm
B) 5 cm
C) 15 cm
D) 20 cm
Correct Answer: C
Solution :
(c): Not Available Suppose A is enlarged with scale factor k to give cone B. Volume of \[B={{K}^{3}}x\] Volume of A \[125={{K}^{3}}\times 27\] \[\frac{125}{125}={{K}^{3}}\] \[\therefore K=\frac{5}{3}\] So, height of the cone \[B=\frac{5}{3}\times \] height of the cone \[A=\frac{5}{3}\times 9=15\]cmYou need to login to perform this action.
