You're making a cover for a rectangular sofa cushion how much fabric do you need to cover the entire cushion with a length of 20 in a width of 48 in and a height of 5 in

2,600 inches of fabric

Step-by-step explanation:

1st

Formula= 2wl+2lh+2wh

Fill in the numbers

2(20)(48)+2(20)(5)+2(5)(48)

2nd

Now solve

2(20)(48)+2(20)(5)+2(5)(48)

1,920 + 200 + 480

3rd

Solve this now

1,920 + 200 + 480

2,600

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
