A circle has a diameter of 16 meters. What is the area of the circle?
The radius of the circle is half of the diameter, so it is 8 meters.
The formula for the area of a circle is: A = πr², where π (pi) is a constant approximately equal to 3.14 and r is the radius.
Substituting the values we have:
A = π(8m)²
A = 64π
Approximating π to 3.14:
A ≈ 64 × 3.14
A ≈ 201.06
Therefore, the area of the circle is approximately 201.06 square meters.
To find the area of a circle, you can use the formula A = πr², where A is the area and r is the radius of the circle.
Given that the diameter of the circle is 16 meters, we can find the radius by dividing the diameter by 2.
r = 16 / 2
r = 8 meters
Now we can substitute the value of the radius into the formula to find the area:
A = π * 8²
A = π * 64
A ≈ 201.062 square meters
Therefore, the area of the circle is approximately 201.062 square meters.
To find the area of a circle, you need to use the formula:
Area = π × r²
where π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.
Given that the diameter of the circle is 16 meters, we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 16 / 2 = 8 meters
Now that we know the radius, we can plug it into the formula to find the area of the circle:
Area = π × 8² = 3.14159 × 8² = 3.14159 × 64 ≈ 201.06 square meters
Therefore, the area of the circle is approximately 201.06 square meters.
