What will happen to the volume of a cylinder if the radius is halved?
A. 1/4 as large
B. 1/5 as large
C. 1/3 as large
D. 1/2 as large

A. 1/4 as large

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

Cut the radius in 1/2

V = pi (1/2r)^2 h

V = pi (1/4) r^2 h

V = 1/4 pi r^2 h

The volume is 1/4 what is was before we cut the radius in 1/2

may i see the picture? it would a lot, xox

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
