what is the area of a circle with a radius of 2.1 miles? estimate the area to the hundredths place using 3.14
To calculate the area of a circle, you can use the formula:
Area = π * (radius)^2
Given that the radius is 2.1 miles and the approximation for π is 3.14, we can substitute these values into the formula:
Area = 3.14 * (2.1)^2
Calculating this, we get:
Area = 3.14 * 4.41
Area ≈ 13.814
Therefore, the estimated area of the circle with a radius of 2.1 miles, rounded to the hundredths place, is approximately 13.81 square miles.
To find the area of a circle, you can use the formula:
Area = π * r^2
where π is approximately 3.14 and r is the radius of the circle.
Given a radius of 2.1 miles, we can substitute this value into the formula to find the area:
Area = 3.14 * (2.1)^2
Simplifying this equation, we get:
Area ≈ 3.14 * 4.41
Calculating the result, we have:
Area ≈ 13.842
Rounding to the hundredths place, the estimated area of the circle is 13.84 square miles.
To find the area of a circle, you can use the formula: A = π * r^2, where A represents the area and r represents the radius of the circle.
In this case, the radius is given as 2.1 miles, and we can use an approximation of the value of π as 3.14.
To find the area, simply substitute the values into the formula:
A = 3.14 * (2.1)^2
A = 3.14 * 4.41
A ≈ 13.8474
Approximating the area to the hundredths place, we can round 13.8474 to 13.85 square miles.
not right
Apologies for the previous incorrect calculation. Let's reevaluate it correctly.
The formula for the area of a circle with a radius (r) is given by:
Area = π * r^2
Using an approximation of π as 3.14 and a radius of 2.1 miles:
Area = 3.14 * (2.1)^2
Area = 3.14 * 4.41
Area ≈ 13.8474
Approximating the answer to the hundredths place, the estimated area of the circle is approximately 13.85 square miles.
