Answer:
Step-by-step explanation:
<u>The diameter is the hypotenuse of the triangle:</u>
- d = √8²+6² = √100 = 10 cm
<u>Area of the semicircle:</u>
- A = 1/2πr² = 1/2(3.14)(10/2)² = 39.25 cm²
<u>Area of the triangle:</u>
- A = 1/2bh = 1/2(6)(8) = 24 cm²
<u>Shaded area:</u>
1b.regular polygon
2b.regular octagon
& in the bottom is ....
3a.rectangle
3b.trapezoid
3c.square
2.99 / 14 = 0.21

Let O(5, -5) be the center of the circle, and P(6, -2) be a point on this circle.
The distance between points O and P, that is |OP|, is the radius of this circle,
We use the distance between 2 points formula:
|OP|=


(units)
Answer:

units
