How to find the area of the shaded region once a right triangle has been removed from a rectangle to create the shaded area?
2 answers:
Answer:
The Area of the shaded region = (Area of the largest circle) – (Area of the circle with radius 3) – (Area of the circle with radius 2). Whatever is left over is the shaded region. The diameter of the largest circle is 10, so its radius is 5 and thus its area is 25π.
Step-by-step explanation:
Area of shaded region =
area of the rectangle - area of right triangle
l = length, b = breadth
Area of rectangle is l × b
b = base, h = perpendicular height
Area of triangle is 1/2×b×h
So (l × b) - (1/2 × b × h)

Step-by-step explanation:
The answer is C. The formula for point slope for is y- y1 = m(x - x1). y-(-2) = 1/2(x-(-3). This is rewritten as y + 2 = 1/2(x + 3)
I believe the correct answer is 15, because 15/8 x 15/1= 225/8 and when you simplify that you get 28 with 1/8 left over.
