The quarter circle pieces are all congruent allowing us to glue them together to form a circle. The circle will be completely inside the square. This circle is as large as possible so it's not spilling outside of the square.
The area of the square is 8*8 = 64 square units
The circle has a radius of 8/2 = 4 units. Use r = 4 and plug this into the area of a circle formula
A = pi*r^2
A = pi*4^2
A = pi*16
A = 16pi
Now subtract the two areas
(area of square) - (area of circle) = 64 - 16pi
The exact answer, in terms of pi, is 64 - 16pi
If your teacher wants you to find the approximate decimal version, then you would use a calculator to find that 64 - 16pi = 13.7345175 approximately. If you end up going with the approximate answer, be sure to follow the instructions on what your teacher wants with rounding.
Answer:
x=3
Step-by-step explanation:
***3x+7=16***
Subtract 7 from each side. You get 3x=9
Divide each side by 3 to isolate x. You get x=3
You can check the answer by plugging in the 3 into the original equation.
You get 3(3)+7=16; which is 9+7=16
Answer:
(-3, -1)
Step-by-step explanation:
As its reflected across the y-axis the y coordinate remains the same but the new x-coordinate is the opposite value.
Here's the equation for one year:
0.03(8000) + 8000
For four years:
4(0.03(8000)) + 8000
0.12(8000) + 8000
To make it simpler/smaller:
1.12(8000) = 8960
You can make 960 more dollars, and you now have $8960
