The diameter of a circle is 2 feet. What is the circle's area?
d=2 ft
Use 3.14 for āš.
The radius of the circle is half the diameter, so it is 1 foot:
r = d/2 = 2/2 = 1 ft
The area of a circle is given by the formula A = šr^2. Plugging in our values for š and r, we get:
A = 3.14 x 1^2 = 3.14 square feet
Therefore, the circle's area is 3.14 square feet.
To find the area of a circle, you need to use the formula:
Area = Ļ * (radius)^2
Given that the diameter is 2 feet, we can find the radius by dividing the diameter by 2:
radius = diameter / 2 = 2 ft / 2 = 1 ft
Now we can substitute the radius value into the area formula:
Area = 3.14 * (1 ft)^2
Simplifying the equation:
Area = 3.14 * 1 ft^2
Area = 3.14 ft^2
Therefore, the area of the circle is 3.14 square feet.
