Answer 1

START.

INTEGER AREA,RADIUS.

PRINT "ENTER THE RADIUS OF CIRCLE - "

AREA=3.14*RADIUS*RADIUS.

PRINT "AREA OF CIRCLE = "

PRINT AREA.

EXIT.

Explanation:

Answer 2

`\pi r^2`

Explanation:

To find the area of a circle, the formula is
`\pi r^2` where r is the radius of the circle.

It’s cool to note that the area of a circle is proportionate to it‘s radius. This is the same with the circumference of a circle (by the way, the formula for that is
`2 \pi r`).

Hope this helped!
