Question

A circle's circumference is approximately 44 cm.

The circle's diameter is approximately:
a. 7 cm
b. 11 cm
c. 14 cm
d. 22 cm

Answer 1

(c)

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

given C ≈ 44 cm , then

πd ≈ 44 ( divide both sides by π )

`(\pi )/(\pi )` d ≈
`(44)/(\pi )` , that is

d ≈ 14 cm

Answer 2

The diameter of a circle with a circumference of approximately 44 cm is calculated by dividing the circumference by π (pi). After performing the calculation, the approximate diameter is found to be 14 cm.

Step-by-step explanation:

The question asks about the diameter of a circle with a given circumference. The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π (pi) is approximately 3.14159, and d is the diameter of the circle. Given that the circumference is approximately 44 cm, we can solve for the diameter as follows:

1. Set up the equation with the known circumference: 44 = πd.
2. Divide both sides by π to isolate the diameter: d = 44 / π.
3. Approximate π as 3.14 for the calculation: d = 44 / 3.14 ≈ 14 cm.

Therefore, the correct answer is c. 14 cm.
