Use your knowledge about the volumes of cones and cylinders to find a volume for a solid hemisphere of radius R.
1 answer:
Answer:
Step-by-step explanation:
The formula for calculating the volume of any sphere is 4/3 of the cubic radius by pi, so you just have to insert the values that you are given in the problem, and you can get an answer, in this case the value for radius is "r" so we are left basically with the next solved fromula:

Answer:
D) y = 12
Step-by-step explanation:
One can use the angle bisector theorem to solve this problem. The angle bisector theorem states:
Where () and (
) are a part of the side that is intersected by the angle bisector and (
) and (
) are the other two sides in the triangle. Substitute in the given values and solve for the unknown.
