x=33.00
Answer:
1. 45
2.40
Step-by-step explanation:
First compute the area of the square like this:
There is two semi circles here, so the sum of the two white
spaces equate the area of a circle.
the radius of the circle is 9/2.
So compute the area of the like this:
And the area of the shaded region is the area of the square minus
the area of the two semi circles, like this:
We are done.
Do you mean (4•10) to the second power or 4•10 to the second power
Can u give brainliest if the answer is true hehe
