-x = -1. Anything “X” equals to the number One. So do Y = -1 + 1.
Multiply all of those numbers
Question 1: 4.375/10 of an hour (or 26.25 minutes)
3=y and 2=x
Pretty sure that’s right
Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
