if the diameter of the circle above is 14 mm, what is the area of the circle?
7 mm2
49 mm2
196 mm2
14 mm2

I believe the correct answer is B. 49 mm2

because the r=7

then do the formula A=3.14*7²

c

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
