Nhambwe kubva pakati kusvika nemuganhu wedenderedzwa inodanwa kunzi taramunyongo, (radius kuChirungu).
- Denderedzigama ndiro rinonzi semi-circle kuChirungu.
- Bandiko (Sector) - iri izwi rinoreva nzvimbo iri pakati pemutaro miviri (radii) yakanyorwa kubva pakati pedenderedzwa kuenda pazvimiso zviviri zvakasiyana zviri pamuganhu wedenderedzwa.

Nhambwe yemuganhu wedenderedzwa
[chinjirudza | chinjirudza mabviro]Muganhu we denderedzwa une nhambwe inopiwa netsazaniso inoti
Pimamuganhu, P = 2πR = πD
Apa π igovano yePimamuganhu neDiameter yeDenderedzwa, R ndiyo taramunyongo yedenderedzwa, D ndiyo Diamater yedenderedzwa. Govano inonzi π, inoda kuyenzana na (22/7) kana kuti 3.14159 nekumwe kunyora.
Nharaunda yeDenderedzwa
