Answer:
A
Step-by-step explanation:
Volume of the cone = 1/3 pi r^2 h = 1005.31 cm^3
Volume of the sphere = 4/3 pi r^3 = 463.25 cm^3
Volume of remaining portion of the cone = 1005.31 - 463.25
= 542.1 cm^3 to nearest tenth
First divide both sides by 12 so u get 5x -4.5 = 3. Now add 4.5 to both sides and u get 5x = 7.5. Now divide 7.5 by 5 and u get 1.5
1/2 times 3/10 equals to 3/20
