Question

Diameter of circle with 2.3 circumference:
a. 0.73
b. 1.46
c. 3.14
d. 4.6

Answer 1

The diameter of a circle with a circumference of 2.3 is found by dividing the circumference by pi, giving a diameter of approximately 0.73.

So, the correct answer is A) 0.73.

Step-by-step explanation:

To find the diameter of a circle when you have the circumference, you use the formula C = πD, where C is the circumference and D is the diameter. The constant π (pi) is approximately equal to 3.14159. If the circumference C is 2.3, you can solve for D by rearranging the formula to:

D = C / π.

So, D = 2.3 / 3.14159, which gives us a diameter approximately equal to 0.73.

Therefore, the correct answer for the diameter of the circle with a circumference of 2.3 is: a. 0.73
