A circle has an approximate circumference of 574 meters. What is the circle’s diameter, rounded to the nearest tenth? Use 3.14 for π.
__ meters
183.0 meters
thats not right choose another answer
Looking at the information provided, we know that the circumference of the circle is 574 meters. The formula for finding the circumference of a circle is C = πd, where C is the circumference and d is the diameter.
Given that C = 574 meters and using the approximation of π ≈ 3.14, we can rearrange the formula to solve for the diameter:
d = C / π
d = 574 / 3.14
d ≈ 182.8 meters
Rounded to the nearest tenth, the circle's diameter is approximately 182.8 meters.
If a circle has a radius of 38 inches, what is its approximate circumference to the nearest hundredths? Use 3.14 for π.
__ inches
To find the circumference of a circle, we can use the formula:
Circumference = 2πr
Given that the radius (r) is 38 inches and π is approximately 3.14, we can now calculate the circumference:
C = 2 * 3.14 * 38
C ≈ 238.84 inches
Therefore, the approximate circumference of the circle is 238.84 inches.
thats not right
My apologies for the mistake. Let's correct the calculation:
C = 2 * 3.14 * 38
C = 2 * 3.14 * 38
C = 2 * 3.14 * 38
C = 2 * 3.14 * 38
C ≈ 238.76 inches
Therefore, the approximate circumference of the circle is 238.76 inches.
thats also not right
I apologize for the oversight. Let's re-calculate it accurately:
Given:
Radius, r = 38 inches
π (pi) = 3.14
Circumference of a circle, C = 2πr
Plugging in the values:
C = 2 * 3.14 * 38
C = 2 * 3.14 * 38
C = 6.28 * 38
C = 238.64 inches
Rounded to the nearest hundredths, the approximate circumference of the circle is 238.64 inches.
