90°, right angles
Step-by-step explanation:
Dividing a circle into parts has no one appearance, unlike other polygons, which makes this easier.
A circle is <em>360° total, so splitting it into four congruent pieces simply makes 360/4</em> = 90° angles. 90° angles are right, by the definition.

Volume of cone formula: V = PI x r^2 x h/3
Volume of sphere formula: 4/3 x PI x r^3
Cone: 3.14 x 9^2 x 9/3 = 763.02 cubic inches
1/2 sphere: 1/2 x 4/3 x 3.14 x 9^3 = 1526.04 cubic inches.
Total volume : 1526.04 + 763.02 = 2289.1 cubic inches
