Answer:
Part 1: 30.42
Part 2: 33.598 (33.6)
Explanation:
Part 1:
First you're going to start by subtracting 142 from 360 to get 218
Then you're going to divide 218 by 360 to get a rounded .61
Then you're going to multiply that by pi (3.14)
.61 x 3.14 = 1.9
Then you're going to square 4
4 x 4 = 16
Then multiply 1.9 x 16
Your answer should be 30.42
Part 2:
Since it gives you the measurment you need, you're going to skip the subtracting and just divide 107 by 360
This gives you .3 (rounded)
Multiply by pi
.3 x 3.14 = .94
multiply by square of 6 (36)
.94 x 36 = 33.84
if you shove it all into a calculator without rounding inbetween at all you get 33.59
