Answer:

4.77

Step-by-step explanation:

because Circumference can be found with this equation

C = 2piR

we need to plug in 15 for Circumference and solve for its radius or R.

15 = 2piR

15/2pi = R

but we need diameter which is 2R so we just need to multiply the answer by 2.

15/2pi × 2 = Diameter

15/pi = D

approximately = 4.77

May i get help please?

Gekata [30.6K]

Answer:

(2,0)

Step-by-step explanation:

Reflection basically flipped upside down. If this image is reflected across x=-2, the D' (said as 'D prime') coordinate would be equal to 2,0.

Prime coordinates are the coordinates of the image after it has been translated.
