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 fraction start1 fraction end 2 in.?

Answer 1

The formula to calculate the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter.

Given that the diameter of the circle is 1/2 inch, we can calculate the circumference using the approximation of π as 3.14.

C = 3.14 * (1/2)
C = 3.14/2
C ≈ 1.57 inches

Therefore, the approximate circumference of the 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

We need to find an integer whose square root is close to 9/4.

To solve this, we will find the square root of some integers and see which one is close to 9/4.

√1 = 1
√2 ≈ 1.414
√3 ≈ 1.732
√4 = 2
√5 ≈ 2.236
√6 ≈ 2.449
√7 ≈ 2.646
√8 ≈ 2.828
√9 = 3

From the values above, we can see that the square root of 9 is 3, which is the closest integer to 9/4.

Therefore, 9/4 is close to the square root of 9.

Answer 4

Bot that’s incorrect

Answer 5

Apologies for the incorrect response.

To find an integer whose square root is close to 9/4, we can square different integers until we find one that is close to 9/4.

Let's try squaring some integers and comparing them to 9/4:

1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16

From the values above, we can see that 3^2 = 9, which is the closest integer to 9/4. Therefore, 9/4 is close to the square root of 9.
