Doing math watch and have no idea what to do

A=πr^2

=3.142×11.2^2

=3.142×125.44

=394.13cm^2

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

other answer is correct. i had used the radius of the radius somehow. a website:
