How do I plot a point on a spherical system?

This is my instructor's instructions:

Problem 8 ‐ MATLAB Write a MATLAB script to generate a plot of the vector A= (8, pi/3, pi/6) in spherical coordinate system. Fully label and title your plot including a grid.

This is what I have so far and I know it isn't right. Help!

clear all;                                  %clear variables
clc;                                        %clear previous window
syms r t rho
pi=3.1415;
r=8;
t=(pi/3);
rho=(pi/6);
z= cos(rho)*(r);
y=r*(sin(rho))*(cos(t));
x=r*(sin(rho))*(cos(t));
figure
[x,y,z]=sphere();
surf(x, y, z)
