Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
It's an irrational number, so you can get as close as you need to, but
you can't write it exactly with numbers. As a decimal, it never ends.
-- The number <em>5.4175</em> is within 0.00003% of the actual value.
-- (5.4175)³ is less than 0.000084% smaller than 159 .
