Diket . L.slimut = 188,4dm^2 , r=6dm Dit: t ..? * L.slimut =Phi x r x s 188,4 = 3,14 x 6 x s 188,4 = 18,84 x s s = 188,4/18,84 = 10 * t = V s^2 - r^2 = V 10^2 - 6^2 = V 100 - 36 t = V 64 = 8 dm
Dit: t ..?
* L.slimut =Phi x r x s
188,4 = 3,14 x 6 x s
188,4 = 18,84 x s
s = 188,4/18,84 = 10
* t = V s^2 - r^2
= V 10^2 - 6^2
= V 100 - 36
t = V 64 = 8 dm
