Question 11A (6 points) Write a function named hemispheres that uses turtle graphics to draw a circle divided into two halves. The function hemispheres takes two parameters: 1. t, a turtle that is used for drawing 2. radius, an integer that is the radius of the circle The turtle t is initially on the edge of the circle at the point that the dividing line should be drawn. The function hemispheres should exit with t in its initial location and orientation. Do not make any assumptions about the initial up/down state of the turtle. The following is correct sample input and output import turtle s # turtle.screen() aTurt = turtle,Turtle() hemispheres (aTurt, 100) Question 11B (14 points) Write a function named multispheres that uses turtle graphics and the function hemispheres in question 11A to draw a sequence of divided circles of specified size and rotation. The function multispheres takes 5 parameters: 1. t, a turtle used for drawing 2. size, the radius of the initial circle raivs 3. ratio, a floating point number that is the ratio of the radii of successive circles 4. angle, the counterclockwise rotation of successive circles 5. num, the number of circles to draw If multispheres is called by the following code, this would be correct graphical output. import turtle ss turtle.Screen() paint turtle.Turtle() multispheres(paint, 188, .8, 8, 4)
