The width of the square is 7 cm. This is also the diameter of the circle.
To find the area of the square, you do 7², which is 49 cm².
To find the area of a circle, you do πr².
The radius is half the diameter, so it's 7 ÷ 2, which is 3.5 cm.
π3.5² ≈ 38.4845100065 cm².
The shaded region is the area of the square minus the area of the circle.
49 - 38.4845100065 = <span>10.5154899935, but because you're using 3.14 to approximate pi, the closest answer is 10.54 cm</span>².
The answer is 10.54 cm².
Hello there!
64 - 2² - (8 + 7)
= 64 - 4 - 15
= 60 - 15
= 45
Let me know if you have any misunderstanding!
As always, I am here to help!
7 tenths I think should be 0.7.
9 times as much as 7 tenths means multiplying 9 by 0.7.
0.7 x 9 = 6.3.
Correct me if I am wrong please!
Unfortunately, I can't really explain it that well, but AB is 6, and A'B' is 2.
6 / 3 = 2
BC is 3, and B'C' is 1.
3 / 3 = 1
Therefore the dilation factor would be 1/3.
Hope this helps! :)
