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 12 in.? (1 point)
To find the circumference of a circle with a diameter of 12 inches, we can use the formula C = πd, where C represents the circumference and d represents the diameter. Approximating π as 3.14, we can substitute the values:
C = 3.14 * 12
C ≈ 37.68 inches
Therefore, the approximate circumference of the circle is 37.68 inches.

94 is close to the square root of what integer?(1 point)
$$
wrong
I apologize for the incorrect response.
To find an integer close to the square root of 94, we can use estimation.
Let's start by trying some perfect squares:
- The square root of 81 is 9. This is less than 94.
- The square root of 100 is 10. This is greater than 94.
Since 94 lies between the squares of 9 and 10, we can estimate that the square root of 94 is close to 9.
