The diameter of the circle above is 16 cm. What is the circumference of the circle? Use = 3.14.


200.96 cm
401.92 cm
50.24 cm
25.12 cm

Respuesta :

16×3.14=50.24
The answer is 50.24cm

Answer: 50.24 cm

Step-by-step explanation: To find the circumference of the circle shown here, start with the formula for the circumference of a circle.

Circumference = 2πr

Notice that here, we're given the diameter instead of the radius. Remember that the radius is equal to half of the diameter. So here, the radius will be equal to half of 16 cm or 8 cm.

So we can plug in 8 cm for r in the formula so we have (2)(π)(8 cm) which is equal to 16π cm. So the circumference of the circle is 16π cm.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have (16)(3.14) which is equal to 50.24.

So the circumference of the circle is approximately equal to 50.24 cm.

I have also attached the circle with the work shown in the image provided.
