Question

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 1/2 in.?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the circumference of a circle with a diameter of 1/2 inch, we can use the formula C = πd, where C is the circumference and d is the diameter.

Given that the diameter is 1/2 inch and using the approximation pi ≈ 3.14, we can substitute these values into the formula to find the circumference.

C = 3.14 × (1/2)
C = 3.14/2
C ≈ 1.57

Therefore, the approximate circumference of a circle with a diameter of 1/2 inch is 1.57 inches.

Answer 2

9/4 is close to the square root of what integer?

Answer 3

[AI-generated answer — Bot GPT 3.5]

To find the square root of an integer close to 9/4, we can simply square integers until we get close to 9/4.

Let's start with the square of 1:
1^2 = 1

Next, let's try the square of 2:
2^2 = 4

The square of 2 is the closest to 9/4 since it is 4 and 9/4 is equal to 2.25. So, 9/4 is close to the square root of 4.
