What is the area of a circle with radius 7? (2022)
Steps
Concepts
Step 1: Identify the formula for the area of a circle, which is Area = πr^2.
Step 2: Find the radius of the circle, which is given as 7.
Step 3: Substitute the radius into the formula: Area = π(7^2).
Step 4: Calculate 7^2, which is 49.
Step 5: Now the formula looks like this: Area = π(49).
Step 6: This simplifies to Area = 49π.
Step 7: To get an approximate numerical value, use π ≈ 3.14.
Step 8: Multiply 49 by 3.14 to get approximately 154.
