Which of the following is an irrational number?
-1 5/29
0.343434
^2/3
87.9821
The irrational number among the given options is ^2/3.
The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of 1/2in.?
The diameter of the circle is 1/2 inches.
Using the formula for the circumference of a circle, we can calculate the circumference:
Circumference = π * diameter
Approximating π as 3.14, we have:
Circumference = 3.14 * (1/2)
Circumference = 3.14 * 0.5
Circumference ≈ 1.57 inches
Therefore, the approximate circumference of the circle with a diameter of 1/2 inch is 1.57 inches.
9/4 is close to the square root of what integer?
To find an integer that is close to the square root of 9/4, we can calculate the square root of 9.
√9 = 3
So, the square root of 9/4 is close to the square root of 9, which is an integer.
Therefore, 9/4 is close to the square root of 9, which is an integer.
