STEP 4: Let's calculate the circle's area. A circle's area is πr², so we need to create a variable to store this value.

• In the LOGIC tab, click on and drag out Float Variable right underneath my_circle.
• Change the variable name from my_var to circle_area.
• Change the value of circle_area from 2.34 to the equation 3.14 * (25/2) ** 2.

3.14 is the value of π, the radius is our diameter divided by 2, and ** 2 is how to square a number in Python!
