The answer is 20. Hope this helps!!!
The complememtn is the angle that adds to the angle to get 90
so
the complement of angle a is b if
a+b=90
so
the comlmement of a 42 degree angle is
42+complement=90
complmement=c
42+c=90
minus 42 both sides
c=48
the measure of the complement is 48 degrees
c is the complement
Fiber optic type of cable is uses a two-number designator consisting of core and cladding measurements.
What does fiber optics serve?
- Fiber optics are used for long-distance and high-performance data networking.
- It is often used in other telecommunications services as well, including internet, television, and telephones.
What methods are used to deploy fiber optics?
- Installing fiber optic cable indoors or outdoors can be done using a variety of installation methods.
- Outdoor cable can be buried or placed in between poles. It may also be blasted or dragged into an innerduct or conduit.
Can fiber optics compete with the internet?
- When compared to normal cable internet and DSL, fiber optic internet is about 20 and 80 times faster.

To solve this problem you must apply the proccedure shown below:
a)
1. You must rewrite the formula for calculate the volume of a sphere:
V=4πr³/3
2. Susbtitue r by d/2 and then solve for d, as following:
V=4π(d/2)³/3
V=(4πd³/8)/3
V=4πd³/24
24V=4πd³
d³=24V/4π
d=∛(24V/4π)
d=2∛(3V/4π)
b) V=4πr³/4
r=d/2
r=(2/3 cm)/2
r=1/3 cm=0.33 cm
V=0.15 cm³
