Answer and Explanation
Your Answer is
Correct Answer is F
Explanation
Because it rotates around the x-axis, the length of SR is the radius of the bottom of the cone=2.
Use the following information to answer questions 41-44.
In the standard (x, y) coordinate plane below, R is located at (1, 0), S is located at (1, 2), and T is located at (4, 0) to form right triangle △RST. The given lengths are in coordinate units.
44. Right triangle △RST will be rotated about the x-axis to form a right circular cone. How long, in coordinate units, is the radius of the cone’s base?
