What is the circumference of a circle with a diameter of 8 kilometers? Estimate the circumference to the hundredths place using 3.14 for π
The circumference of a circle can be found by using the formula: C = πd, where C is the circumference and d is the diameter.
In this case, the diameter is given as 8 kilometers. Substitute this value into the formula:
C = 3.14 * 8
C = 25.12
Therefore, the circumference of the circle with a diameter of 8 kilometers is approximately 25.12 kilometers.
The circumference of a circle can also be found using the formula: C = 2πr.
In this case, the radius is given as 3 feet. Substitute this value into the formula:
C = 2 * 3.14 * 3
C = 18.84
Therefore, the circumference of the circle with a radius of 3 feet is approximately 18.84 feet.
The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius.
In this case, the diameter is given as 16 yards. To find the radius, we divide the diameter by 2:
r = 16 yards / 2
r = 8 yards
Substitute this value into the formula:
A = 3.14 * (8)^2
A = 3.14 * 64
A ≈ 200.96
Therefore, the area of the circle with a diameter of 16 yards is approximately 200.96 square yards (rounded to the hundredths place).

Question
What is the circumference of a circle with π what's the diameter of 5.75 miles? Estimate the circumference to the hundredths place using 3.14
To find the circumference of a circle, we use the formula C = πd, where C is the circumference and d is the diameter.
In this case, the diameter is given as 5.75 miles. Substitute this value into the formula, using π as 3.14:
C = 3.14 * 5.75
C ≈ 18.065
Therefore, the circumference of the circle with a diameter of 5.75 miles, using π as 3.14, is approximately 18.07 miles (rounded to the hundredths place).
