1 i dont need a explanation

Part 1: 30.42

Part 2: 33.598 (33.6)

Step-by-step 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

109 is the nearest whole number/final answer! : )

table 3 represents a direct variation function. : )
