Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. the diameter of the circle is 14 in.

Option

Step-by-step explanation:

we know that

The area of the region that is inside the square and outside the circle is equal to the area of the square minus the area of the circle

see the attached figure to better understand the problem

Step 1

Find the area of the square

Remember that

The area of the square is

where

b is the length side of the square

we have

substitute

Step 2

Find the area of the circle

Remember that

The area of the circle is equal to

we have

substitute

Step 3

Find the area of the region

i can answer this question sweetie!

step-by-step explanation:

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
