Matamataig

Faic pi (àireamh)

Cleachdar π ann an matamataig a chomharraich an riochd eadar cearcall-thomhas agus trast-thomhas a' chearcaill. Is e àireamh neo-raiseanail a tha ann an π, ach tha luach π faisg air 22/7 neo 3.142. Tha sin ri ràdh: π × trast-thomhas = cearcall-thomhas. Cuideachd tha π × radius a' chearcaill ceàrnagaichte co-ionnann ri farsaingeachd a' chearcaill.
