What is the area of a circle with a radius of 2.1 miles? Estimate the area to the hundredths place using 3.14 for π
I apologize for the mistake once again. Let me calculate it correctly.
The formula for the area of a circle is A = π * r^2. Plugging in the given radius of 2.1 miles and using 3.14 for π:
A = 3.14 * (2.1)^2
= 3.14 * 4.41
≈ 13.8534
Rounding to the hundredths place, the estimated area of the circle with a radius of 2.1 miles is approximately 13.85 square miles.
The formula for the area of a circle is A = π * r^2, where A is the area and r is the radius.
Plugging in the given radius of 2.1 miles and using 3.14 for π:
A = 3.14 * (2.1)^2
= 3.14 * 4.41
≈ 13.814
Therefore, the estimated area of the circle with a radius of 2.1 miles is approximately 13.814 square miles.
thats wrong bot

still wrong
To find the area of a circle, we use the formula A = π * r^2, where A is the area and r is the radius.
Given the radius of 2.1 miles, and using π ≈ 3.14, we can substitute the values into the formula:
A = 3.14 * (2.1)^2
To calculate, we start with squaring the radius:
A = 3.14 * 4.41
Next, we multiply 3.14 by 4.41:
A = 13.8294
Rounding to the hundredths place, the estimated area of the circle is approximately 13.83 square miles.
To find the area of a circle, you can use the formula A = πr^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.
First, square the radius: 2.1^2 = 4.41.
Next, multiply the squared radius by π (which we will approximate as 3.14 for this estimation): 4.41 * 3.14 = 13.8194.
Finally, round the result to the hundredths place, which is two decimal places: 13.8194 rounded to the hundredths place is approximately 13.82.
Therefore, the estimated area of a circle with a radius of 2.1 miles is 13.82 square miles.
