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
.(1 point)
___? square miles
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius.
In this case, the radius is given as 2.1 miles.
Substituting the values into the formula:
A = 3.14 * (2.1)^2
Calculating:
A ≈ 3.14 * 4.41
A ≈ 13.8174
Rounding to the hundredths place:
A ≈ 13.82 square miles
So, the estimated area of the circle is 13.82 square miles.
Incorrect...
Apologies for the mistake.
The correct calculation should be:
A = πr^2
A = 3.14 * (2.1)^2
A = 3.14 * 4.41
A ≈ 13.82234
Rounding to the hundredths place:
A ≈ 13.82 square miles
So, the estimated area of the circle is 13.82 square miles.
To find the area of a circle, you can use the formula A = πr^2. The value of Pi (π) is approximately 3.14.
To calculate the area of a circle with a radius of 2.1 miles, you can substitute the given values into the formula:
A = 3.14 * (2.1 miles)^2
Now, let's do the calculation:
A = 3.14 * (2.1 miles)^2
A = 3.14 * 4.41 miles^2
A ≈ 13.84 square miles
Therefore, the estimated area of a circle with a radius of 2.1 miles is approximately 13.84 square miles when rounded to the hundredths place.
