minus-squareidegenszavak@sh.itjust.workslinkfedilinkarrow-up10arrow-down1·2 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-up8arrow-down1·edit-22 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.

πr^2?

No, its r^π √2
