How to find the circumference with a radius​

Mathematics

Answer:

The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.

Answer:

the circumference is pi*diameter. diameter is radius*2, and so (radius*2)*pi is the circumference

If the radius of the circle is 14 meters, find the length of arc RS<br><br> (brainliest given)
Travka [436]

Answer:

s=14(116)

s = 1624

(This is the arc length for <u>RS</u>)

The line T to R cuts the circle in half. Half of a circle in degrees is 360/2. Which is 180.

Now we take the known angle and subtract it from 180 to get the unknown angle which is the angle of RS.

[180-64 = 116]

Arc length = radius * theta

Arc length = 14 * 116 = 1624

[FOR TS BELOW]

s=r(theta)

s= 14(64)

s = 896 (arc length for <u>TS</u>)
