The formula is used to find the diameter of circle is: d = \frac{C}{3.14}

The diameter of circle is 5.1 cm

<em><u>Solution:</u></em>

Given that,

Circumference (C) of a circle is 16 cm

<em><u>The formula for circumference of circle when diameter is given is:</u></em>

C = \pi d\\\\\pi \text{ is a constant equal to 3.14}\\\\C = 3.14d

<em><u>Rearrange the formula to get "d"</u></em>

Divide both sides by 3.14

d = \frac{C}{3.14}

The above formula is used to find the diameter of circle

Given that, circumeference = C = 16 cm

Substituting we get,

d = \frac{16}{3.14}\\\\d = 5.095 \approx 5.1

Thus diameter of circle is 5.1 cm

mart [117]

Answer:

A

Step-by-step explanation:

Using the sine ratio in the right triangle

sin40° = \frac{opposite}{hypotenuse} = \frac{AC}{AB} = \frac{AC}{7}

Multiply both sides by 7, thus

AC = 7sin40° → A
