By definition, the arc length is given by:
s = R * teta
Where,
Radio
Teta: arc angle measured in radians.
We have then that the length of the arc in this case is:
s = (7.9) * (180-66.4)) * (pi / 180)
s = 15.7 cm
Answer:
The length of the AD arc is:
s = 15.7 cm

a rectangle has a width of 4 cm and a length of 8cm is scaled by a factor of 6.what are the side lengths of the scaled copy

Answer:

$\huge\boxed{\text{Width: } 24 \ \ \ \text{Length: } 32}$

Step-by-step explanation:

When we scale an object by a scale factor, the side lengths become the scale factor times bigger than the previous sides. Therefore, with a scale factor of 6, the side lengths would be multiplied by 6.

$4 \cdot 6 = 24\\\\4 \cdot 8 = 32$
