explain your answers and check for mistakes in your work.
I apologize for the error in my previous responses.
To find the circumference of a circle, we use the formula:
Circumference = 2 * pi * radius
Substitute the value of pi as 3.14 and the radius as 279 inches:
Circumference = 2 * 3.14 * 279
Circumference = 1751.08 inches
To find the area of a circle, we use the formula:
Area = pi * (radius)^2
Substitute the value of pi as 3.14 and the radius as 279 inches:
Area = 3.14 * (279)^2
Area = 3.14 * 77841
Area = 244400.94 square inches
Therefore, the correct answers are:
Circumference: 1751.08 inches
Area: 244400.94 square inches
then the circumference should be 1752.12
You are correct. I made a mistake in rounding the circumference. The correct rounded answer for the circumference will be 1752.12 inches.
Therefore, the correct answers are:
Circumference: 1752.12 inches
Area: 244400.94 square inches
check your work for the area.
I apologize for the error in my previous responses. Let's recheck the calculation for the area of the circle with a radius of 279 inches.
Given:
Radius = 279 inches
Pi (π) ≈ 3.14
The formula for the area of a circle is:
Area = π * (radius)^2
Substitute the values:
Area = 3.14 * (279)^2
Area = 3.14 * 77941
Area = 244790.74 square inches
Therefore, the correct answer for the area of the circle with a radius of 279 inches is 244790.74 square inches.
