Determine whether each figure has rotational symmetry , line symmetry , both, or neither .

answer:

The first has rotational and line symmetry since it can be split in half by 6 small rotational segments

The second has none

The third Has line symmetry

And the fourth has none

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
