Lorico [155]

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either

This means we are to find the volume.

The volume of a sphere is given as:

4/3πr³

We are given Diameter of the fish bowl = 16 inches

Radius = Diameter/2 = 16 inches/2

= 8 inches
