Question 560343: Please help me solve this :
A semi Circle has a diameter of 20.9cm
Work out the perimeter of the semi circle
Give your answer to an appropriate degree of accuracy.
Now i know you have to do pi * diameter,
SO - 3.142 *20.9 = 65.67 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! SO: 3.142 *20.9 = 65.67
----
That is the perimeter of the whole circle.
You want half of that.
You also need the base of the semi-circle, which is the diameter.
---
Perimeter = (65.67/2) + 20.9 = 53.74
