How to find the area of the circle with the diamiter of 28
A = pi * r^2
i got it now mrs.sue thanks
I think you mean "Ms. Sue"
To find the area of a circle with a diameter of 28, you can use the formula for the area of a circle: A = πr², where A is the area and r is the radius of the circle.
Step 1: Find the radius
Since the diameter is given, you can divide it by 2 to find the radius. In this case, the radius would be 28/2 = 14.
Step 2: Calculate the area
Now that you have the radius, substitute the value of the radius into the formula: A = π(14)².
Step 3: Simplify the equation
Calculate the squared value of the radius: (14)² = 196.
Multiply the squared radius by π: A = 196π.
Step 4: Approximate the answer
If you need an approximate value, you can use the approximation for π, which is 3.14, to get the final answer. Multiply 3.14 by 196: A ≈ 615.44.
Therefore, the area of a circle with a diameter of 28 would be approximately 615.44 square units.
