2. DanJS

a half circle and a rectangle

3. DanJS

Are there any measurements , or just variables

4. DallasLifeBaby01

yeah sorry it not a good drawing

5. DallasLifeBaby01

no its just the shape

6. DanJS

ok... one moment

The total area, is half the area of the circle radius R, Plus, A rectangle with side lengths 2R and L

9. DanJS

Area Circle = pi * Radius^2 Area Rectangle = Length * Width

10. DallasLifeBaby01

okay thanks

11. DanJS

$Total Area = \frac{ 1 }{ 2 }\pi*R^2 ~~+~~2R*L$

12. DanJS

Half a circle, plus the rectangle

13. DanJS

So to explain the steps.. 1) draw a radius of the circle 2) the width of the rectangle is 2 times the radius 3) Let the length of rectangle be L then what i explained above

14. DallasLifeBaby01

okay thanks this helps so much!
