pororapa he ahua ahuahanga i puta mai i o raatau porowhita ma te huringa affine.
ihirangi
tātai rohe
Ko te horahanga o te ellipse (S) he rite ki te hua o te roa o ona haurua me te tau. π:
S = π *a * b
Tuhipoka: mō ngā tātaitanga te uara o tētahi tau π whakaawhiwhia ake ki 3,14.
He tauira o te raruraru
Kimihia te horahanga o te ellipse mena he 2 cm me te 4 cm ona tuaka.
Te whakatau:
Ka whakakapihia e matou nga raraunga e mohiotia ana e matou i runga i nga tikanga o te raruraru ki te tauira: S u3,14d 2 * 4 cm * 25,12 cm uXNUMXd XNUMX cm2.
