minus-squareidegenszavak@sh.itjust.workslinkfedilinkarrow-up0·3 months agoWhy would i calculate r? I need only the area. See? Why would I waste my time for an extra calculation.
minus-squarestebo@lemmy.dbzer0.comlinkfedilinkarrow-up1·edit-23 months agoJust do it in your head? The diameter is 5.62, so the area is π*2.81², which is more efficient to type in your calculator than π*5.62²/4. You’re the one wasting time.
