Step-by-step explanation:
How to find x:
tan(45)= 5/x
x = 5/tan(45) [Find on calculator]
How to find y:
Pythagoras' theorem:
a² + b² = c²
5² + x² [value found in first part] = y²
Square root the sum of 5² + x² and the y²
The answer of the square root of the sum is the value of y
"The graph below" is an important source of information here. In fact, you
actually can't answer the question without it. That's a big part of the reason
it was printed right there in the same place you copied the question from.
The formula for volume of a sphere is:
V = 4/3 * PI * r^3
Replace r with with given radius:
V = 4/3 * pi * 17^3
V = 4/3 * PI * 4913
You don't give the choices, but anything like the two equations I gave could be correct. Might even multiply the 4/3 by r^3?
If you list the choices I can tell you which one.
Answer:
Simplify each side of the equation by removing parentheses and combining like terms.
Use addition or subtraction to isolate the variable term on one side of the equation.
Use multiplication or division to solve for the variable.
