estimate the area of a circle with a radius of 27 meters use 22/7 for pi
The formula for the area of a circle is A = πr^2, where r is the radius.
Plugging in the given values, we get:
A = 22/7 x 27^2
A ≈ 22/7 x 729
A ≈ 2,292
Therefore, the estimated area of the circle with a radius of 27 meters is about 2,292 square meters.
To estimate the area of a circle with a radius of 27 meters using the approximation 22/7 for π, follow these steps:
1. Calculate the area using the formula: Area = π × radius²
Area = (22/7) × 27²
2. Simplify the expression: Area = (22/7) × 729
3. Multiply the fraction by the whole number: Area = (22 × 729) / 7
4. Evaluate the expression: Area = 16038 / 7
5. Divide the numerator by the denominator to find the decimal approximation: Area ≈ 2291.14 square meters
Therefore, the estimated area of a circle with a radius of 27 meters, using 22/7 for π, is approximately 2291.14 square meters.
To estimate the area of a circle, you can use the formula:
Area = π * r^2
Where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.
In this case, the radius is given as 27 meters.
Let's plug the values into the formula:
Area = (22/7) * (27)^2
Now, calculate the square of the radius:
Area = (22/7) * (729)
Next, evaluate the multiplication:
Area = 22 * 729 / 7
Area ≈ 22 * 104.14
Area ≈ 2291.08
Therefore, the estimated area of a circle with a radius of 27 meters is approximately 2291.08 square meters.
