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 .(1 point)
The circumference of a circle is calculated using the formula C = πd, where C is the circumference and d is the diameter.
Using this formula, the circumference of a circle with a diameter of 8 kilometers can be calculated as follows:
C = πd
C = 3.14 × 8
C = 25.12 kilometers
Therefore, the estimated circumference is 25.12 kilometers.
The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference and r is the radius.
Using this formula, the circumference of a circle with a radius of 3 feet can be calculated as follows:
C = 2πr
C = 2 × 3.14 × 3
C = 18.84 feet
Therefore, the estimated circumference is 18.84 feet.
The area of a circle can be calculated using the formula A = πr^2, where A is the area and r is the radius. Since the diameter is given, we can find the radius by dividing the diameter by 2.
The radius of the circle with a diameter of 16 yards is 16 / 2 = 8 yards.
Using the formula, the area of the circle can be calculated as follows:
A = 3.14 * (8)^2
A ≈ 200.96
Therefore, the estimated area is 200.96 square yards, rounded to the hundredth place.
