The circumference of a circle can be calculated using the formula:
Circumference = π * diameter
Given that the diameter is 3.25 meters, and using π = 3.14, we can calculate:
Circumference = 3.14 * 3.25 = 10.255 meters
Rounding to the hundredths place, the estimated circumference is 10.26 meters.
Therefore, none of the given options is correct.
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a mathematical constant approximately equal to 3.14, and d is the diameter of the circle.
In this case, you are given a diameter of 3.25 meters. To find the circumference, you can substitute this value into the formula:
C = 3.14 * 3.25
Multiplying these values together gives you:
C = 10.235
However, the question asks us to estimate the circumference to the hundredths place using 3.14 for π. To do this, we round the result to two decimal places:
C = 10.24 meters
Therefore, the correct answer is:
10.24 meters
To find the circumference of a circle, you can use the formula: circumference = π x diameter.
Given that the diameter is 3.25 meters and using the approximation value of π as 3.14, you can substitute these values into the formula to estimate the circumference.
Circumference = 3.14 x 3.25
Calculating this:
Circumference ≈ 10.21 meters
So, the estimated circumference of the circle is 10.21 meters, rounded to the hundredths place.
