A circle is cut out of a piece of plywood that is 10in. square. Find the area of the circle and How many square inches of plywood are thrown away? If you can solve this AND show your work you get brainlist.

Below in bold.

Step-by-step explanation:

The radius of the circle = 1/2 * 10 = 5 in,

Area of circle = pi * (5)^2

= 25pi

= 78.54 in^2

Amount of wood thrown away

= area of square - area circle

= 10^2 - 78.54

= 21.46 in^2.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
