(C)x ∈ A ⋃ C
Step-by-step explanation:
A diagram has been created and attached for more understanding.
If the overlap of circles B and C is labeled x.
Then:
If x is contained in the intersection of B and C, it means that:
Finally:
The correct options are A, B and C.
Answer:
Step-by-step explanation:
Radius=r. Diameter=d. C=circumference. A=area
Starting from the center of the circle any line drawn to any point on the circumference of the circle is the radius, if the line is drawn from one point on the circumference to another point on the circumference through the centre of the circle that is the diameter. The circumference of the circle is the perimeter of the circle.
