Answer:
A.
Step-by-step explanation:
Surface area of the original cone
When, radius is quadrupled and slant height is reduced to one sixth
Plug the above values of r and in equation (1), new surface area becomes:
T=2n+3
considering n has no other values given
Answer:
x=8
Step-by-step explanation:
5x+14 = 6x+6
8=x or x=8
