Help pls so people say it’s none of these but idk I am confused.

Volume =

2512 = 3.14 × r^2 × 8

Dont get confused try to understand : )

20 cm

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We are given the volume and the height

2512 = pi r^2 *8

Divide each side by 8

2512/8 = pi r^2 *8/8

314 = pi r^2

Divide each side by pi

314/3.14 = 3.14 r^2 /3.14

100 = r^2

Take the square root of each side

sqrt(100) = sqrt(r^2)

10 = r

We want to find the diameter

d =2r

d =2(10)

d =20

The diameter is 20 cm

your answer would be 10x - 1

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
