What is the area of a circle that is 3 inches?

28.26 in²

Step-by-step explanation:

Radius = 3

Area = pi × r²

3.14 × 3²

28.26

28.27 inches^2

Step-by-step explanation:

The area of a circle can be found using:

a= pi* r^2

We know r, or the radius is 3, so we can substitute that in

a= pi * 3^2

a=pi *9

a=28.2743339...

The area is about 28.27 inches^2

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

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|
