Answer:
R' = (-2, -3)
Step-by-step explanation:
When a figure undergoes a 180degree rotation, both the (x) and (y) coordinates are multiplied by (-1). The coordinates of the given point are (2, 3). Multiply both of these numbers to fine (R'), that is point (R) after it undergoes its rotation. The coordinates of (R') are (-2, -3).
I think it is 39a or whatever unit you're using
A shape can have more then 360 degrees of rotational symmetry is false
Answer:
approx. 113.1
Step-by-step explanation:
Area formula: A= pi* (r^2)
12/2 = 6, so r=6
A= pi * (6^2)
A= pi * (36)
A = approx. 113.1
