The radius r used in below equations would equal 2in because it is half the given diameter of 4in.
The volume of the cone would be
$V = \frac{1}{3} \pi r^2h \\ \\ V = \frac{1}{3} \pi (2in)^2(6in) = 8 \pi\ in^3$

The volume of a cylinder with the same dimensions would be
$V = \pi r^2h \\ 
V = \pi (2in)^2(6in) = 24 \pi in^3$

The cylinder is 24 - 8 = 16 cubic inches greater.

18(x + 1) = -54 pls help solve this...

serg [7]

Answer:

x = 71

Step-by-step explanation:

18(x + 1) = -54

to start off, subtract 18 from both sides

18 - 18(x + 1) = -54 - 18

that should give you

x + 1 = 72

(its safe to take out paranthesis from problem by now) now take away 1 from each side

x + (1 - 1) = 72 - 1

that should give you

x = 71
