I know that for a Semi-Circle = . From this find out of the Semi-Circle.

`pi = `
 
 
SolutionSemi-Circle FormulaArea Formula
Area of Semi-Circle
Area `(A) = 1/2 pi r^2`
Circumference `(C) = pi r = (pi d)/2`
Perimeter `(P) = pi r + 2 r`
Diameter `(d) = 2 r`

Example :
I know that for a Semi-Circle Radius = 10 . From this find out Area of the Semi-Circle.

`"Here radius "(r)=10" (Given)"`

``

`"Diameter "(d)= 2 r`

` = 2 * 10`

` = 20`

``

`"Circumference" = pi r`

` = 22/7 * 10`

` = 220/7`


`"Perimeter" = pi r + 2 r`

` = 22/7 * 10 + 2 * 10`

` = 220/7 + 20`

` = 360/7`


`"Area" = (pi r^2)/2`

` = (22/7 * (10)^2)/2`

` = 1100/7`
