Find for Semi-Circle Radius=7. Find Area

Solution:
Your problem `->` for Semi-Circle Radius=7. Find Area


`"Here radius "(r)=7" (Given)"`


`"Diameter "(d)= 2 r`

`=2 * 7`

`=14`


`"Circumference" = pi r`

`=22/7 * 7`

`=22`


`"Perimeter" = pi r + 2 r`

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

`=22 + 14`

`=36`


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

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

`=77`
