The formula for the area of a circle is a = <span>πr², r being the radius.
To tackle this problem, find the area of the square and then subtract the area if the circle:
Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314
Area of square - area of circle = 400 - 314 = 86 m²
Hope this helps!

-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
