Q
Q: What is the area of a circle with radius r?
Solution:
The area of a circle is given by the formula A = πr^2.
Steps: 5
Show Steps
Step 1: Understand that a circle is a round shape with all points the same distance from the center.
Step 2: Know that the distance from the center to the edge of the circle is called the radius (r).
Step 3: Learn the formula for the area of a circle, which is A = πr^2.
Step 4: In the formula, π (pi) is a special number approximately equal to 3.14.
Step 5: To find the area, you need to square the radius (multiply r by itself) and then multiply that by π.
