B. Distance between two points (x1, y1) and (x2, y2) is governed by the formula

Write a program to compute D given the coordinates of the points. C. A point on the circumference of a circle whose center is (0, 0) is (4,5). Write a program to compute perimeter and area of the circle. (Hint: use the formula given in the Ex. 3.11)

D. The line joining the points (2,2) and (5,6) which lie on the circumference of a circle is the diameter of the circle. Write a program to compute the area of the circle.
