Answer 1

Hello there,
I will write the steps to the algorithm below :-
1.START
2.INTEGER AREA,RADIUS
3.PRINT "ENTER THE RADIUS OF CIRCLE - "
4.AREA=3.14*RADIUS*RADIUS
5.PRINT "AREA OF CIRCLE = "
6.PRINT AREA
7.EXIT

Answer 2

3.14 times the radius squared equals the area of a circle. Know how to identify the circumference of a circle given the circumference using this equation.

Algorithm to find the area of a circle :

3.14 times the radius squared equals the area of a circle. Know how to identify the circumference of a circle given the circumference using this equation.

           Step 1: Start

           Step 2: Get an integer input from user for AREA and RADIUS.

           Step 3: Print the statement "Enter the Radius of Circle: "

           Step 4: Calculate the area of the circle using the formula of $\pi r^{2}$

            (r - Radius)

            Step 5: Print the statement "Area of Circle:"

           Step 6: Print Area

            Step 7: Stop
