To find the arc length of the semi circle we can find the circumference of the full circle and divide by 2.
The radius of the circle is 8 / 2 = 4
Circumference Formula: 2πr
= 2π(4)
= 8π or 25.12
Now, divide by 2 to find the arc length of the semi circle.
25.12 / 2 = 12.56
Finally, divide by 3.14 to find the arc length in terms of pi.
12.56 / 3.14 = 4π
Therefore, the arc length of the semi circle is 4π
Best of Luck!
Length of arc of semicircle is 12.56 units.
Given that;
Diameter of Semi-circle = 8 unit
Find:
Length of arc of semicircle
Computation:
Radius of Semi-circle = 8/2
Radius of Semi-circle = 4 unit
Length of arc of semicircle = πr
Length of arc of semicircle = (3.14)(4)
Length of arc of semicircle = 12.56 units
