Answer:

D

Step-by-step explanation:

The formula for volume of cone is  V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

Answer:

The measure of the fourth angle = 137.1°

Step-by-step explanation:

Let x = the measure of the fourth angle

Sum of all 4 interior angles in a quadrilateral equal 360°

so

x + 23.5° + 99° + 100.4° = 360°

x + 222.9° = 360°

              x = 360° - 222.9°

              x = 137.1°
