Answer: The formula for the circumference of a circle is given by:
C = π * d
where C is the circumference and d is the diameter of the circle.
Given that the diameter is 3.2 inches and the estimated value of π is 3.125, we can calculate the circumference using the given diameter:
C = π * d
C = 3.125 * 3.2
C ≈ 9.875 inches
Now, you are asked to multiply this calculated circumference by 2.4 using the new value of π. Let's denote this new value of π as π_new:
C_new = 2.4 * C
Substitute the value of C:
C_new = 2.4 * 9.875
C_new ≈ 23.7
So, the new value of the calculated circumference using the estimated value of π_new is approximately 23.7 inches.
