What is the area if the diameter is 14?
The area of the circle is 154 square feet.
What is the area of this circle use 3.14 for pi?
the area of a circle is equal to pi r square that is 3.14×3×3 = 28.26.
How do you use 3.14 for pi?
If we want the exact circumference or area of a circle, we leave the symbol π in the answer. We can get an approximate answer by substituting 3.14 as the value of π . We use the symbol ≈ to show that the result is approximate, not exact.
What’s the area of a 12 inch circle?
To find the area of a circle, you need to use the formula A=π⋅r2 ; therefore the area A is π⋅62≈113 square inches.
What is the area of a 10 inch circle?

How do you use pi to find the area of circle?
The area of a circle is pi times the radius squared (A = π r²).
How do we calculate the area of a circle?
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
What is the formula to calculate pi?
The formula for the value of pi is the ratio of the circumference of a circle to its diameter. In the ratio form, it is π = Circumference/Diameter.
How do you find area using pi?
How to calculate the area of a circle?
Area of a circle = π * r 2. Area of a circle diameter. The diameter of a circle calculator uses the following equation: Area of a circle = π * (d/2) 2. Where: π is approximately equal to 3.14. It doesn’t matter whether you want to find the area of a circle using diameter or radius – you’ll need to use this constant in almost every case.

How is the diameter of a circle determined?
The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart. This is the area contained within a circle with the specified diameter.
