Answer: (- 15, 20)
Step-by-step explanation:
In the format (x – h)² + (y – k) = r², the center of the circle is at point (h, k).
-> The negatives in the first equation, bolded and underlined, means we change the sign of positive to negative or negative to positive.
(x <u>-</u> h)² + (y <u>-</u> k) = r²
(x + 15)² + (y - 20)² = 100
(x <u>-</u> 15)² + (y <u>+</u> 20)² = 100
(x <u>- 15</u>)² + (y + <u>20</u>)² = 100
(- 15, 20)
We can also see this with graphing. See attached.
The center of the circle will be at point (- 15, 20).

Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle =
⇒ area =
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²
