Answer:
Why don't we see the ground coming toward us?
Step-by-step explanation:
Why don't we see the ground coming toward us? We have less gravitational force than the earth. ... It has a lot of mass, so it feels the earth's gravitational force less than smaller objects do. It has more mass than the earth, so it stays in one place while the earth orbits it.

Equation: 
Solution: 
Step-by-step explanation:
A square is a quadrilateral that has four equal sides and four equal angles that measure 90 degrees (An angle that measures 90 degrees is also known as "Right triangle".
By definition, the perimeter of a square can be calculated by multiplying the length of any of its sides by 4 (because all its sides are congruent, as it was explained before).
In this case, you know that the perimeter of this square is 36 feet.
Then, you can write the following equation to model this situation:
Where "s" is the length of any side of the square.
Then, you need to solve for "s" in order to find its value. Divide both sides of the equation by 4.
You get that it is:
Answer:
21.5cm²
Step-by-step explanation:
First you find out the Area of the square itself which is 100cm² (squared). Then you Find the Area of the circle. The formula to find the area of a circle is π × Radius². So you find the diameter of the circle (which is 10) and divide that by 2 to find the radius. So the radius is 5 but then you need to square 5 which is 25. Then you multiply 25 with pi which is 78.5 so the area of the circle is 78.5cm². Now what you have to do is subtract the area of the square and the area of the circle to find the area of the shaded region. 100-78.5 is 21.5cm ² and that is the answer.
