Step-by-step explanation:
Answer:
Formula of circumference: pie(use 3.14 or 22/7) x radius (half of diameter or already given radius) x 2
100 + 100 = 200.
Half of 50(diameter) is 25(new radius). 25(radius) x 3.14(pie) x 2(it always will be there when finding circumference) = 157.
200 + 157 is = 357.
357 is your answer.
Consider the attached figure. The height CD cuts the triangle exactly in half. This means that

Moreover, since CD is the height of the triangle, we know that ACD is a right triangle. We know the hypothenuse AC to be 20 feet because it is a side of the triangle, and we just found out that AD is 10. We can use the pythagorean theorem to deduce

So, the area is
