There are 3 more dots above the 13 than are above the 12, so the appropriate choice is ...
... A. 3
Angles B and D are congruent so:
(360-112-74)/2=87°
Answer:
This is very easy. First find the volume of the cube, and then add it to the volume of the hemisphere to find the total volume.
The volume of the cube is length x width x height: 8 x 8 x 12 = 768 cm
The volume of the hemisphere is (2/3)πr³ : (2/3)π(4)³ = 134.04 cm
*Radius is 4
Now add: 768 + 134.04 = 902.04 cm
