Area of SemiCircle
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 SemiCircle Radius = 10 . From this find out Area of the SemiCircle.
`"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`
