Acentral angle of a circle measures 1.2 radians, and the length of the related intercepted arc measures 6 cm. what is the diameter of the circle? a) 2.5 cm b) 3.5 cm c) 5 cm d) 10 cm

d = 2r = 2(5 cm) = 10 cm  (Answer D)

Step-by-step explanation:

The arc length formula is s = r·Ф, where r is the circle radius and Ф is the central angle in radians.  Here we need to find r, and from r we need to find d.

If s = r·Ф, then s / Ф = r.  In this particular case, r = (6 cm) / (1.2 rad) = 5 cm.

If r = 5 cm, then d = 2r = 2(5 cm) = 10 cm  (Answer D)

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
