Answer: A=351.68 cm²
Step-by-step explanation:
To find the area of the shaded region, we would subtract the area of the circle by the area of the inner circle.
Area of Circle
Area of inner (white) circle
Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.
Step-by-step explanation:
p(R)=18/48 is the probability of the question
Answer: and is a right angle .
Step-by-step explanation:
Given : A reflection is a transformation that maps point Q in a figure over a line, AB, such that for point C at the intersection of AB and QQ'.
We know that reflection creates a image equidistant from the line of reflection.
Thus,
Also in reflection , a line drawn from the point is perpendicular to the line of reflection.
Therefore, is a right angle
