Answer:
523.6
Step-by-step explanation:
just put it through the formula for the volume of a sphere
Answer:
Move the constant to the right. Step 3: Take half of the x-term coefficient and square it. Add this value to both sides. Step 4: Simplify right side. Step 5: Write the perfect square on the left. Step 6: Take the square root on both sides of the equation. Step 7: Solve for x. Solve equation x2 - 4x + 3 = 0.

If 15^2 = 9^2 +12^2, the triangle satisfies the Pythagorean Theorem for a right triangle.
Is (15^2 = 81 + 144)?
Is (225 = 225)? Yes
Therefore the given triangle is a right triangle. Let the vertex of the right angle be C, the leg AC is 12, the hypotenuse AB is 15 and the leg BC is 9. The line perpendicular to the hypotenuse at a point D that connects to the vertex C is the "height" of the triangle ABC. It can be shown that the three angles of the triangle ABC are equal to those of triangle CBD. Thus triangle ABC is similar to CBD. The problem is to find the lenght of the line CD.
Using proportions of corresponding sides we have
CD/9 = 12/15
CD = 9*12/15
CD = 36/5
Answer: the line is 7.2 cm.
