Céimeanna chun Cothromóidí Líneacha a Réiteach

Ríomh cumhacht 25 de 2 agus faigh 625.

$$10000cm^{2}=2\pi \times 625+2\pi \times 25h$$

Méadaigh 2 agus 625 chun 1250 a fháil.

$$10000cm^{2}=1250\pi +2\pi \times 25h$$

Méadaigh 2 agus 25 chun 50 a fháil.

$$10000cm^{2}=1250\pi +50\pi h$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$10000m^{2}c=50\pi h+1250\pi$$

Roinn an dá thaobh faoi 10000m^{2}.

$$\frac{10000m^{2}c}{10000m^{2}}=\frac{50\pi \left(h+25\right)}{10000m^{2}}$$

Má roinntear é faoi 10000m^{2} cuirtear an iolrúchán faoi 10000m^{2} ar ceal.

$$c=\frac{50\pi \left(h+25\right)}{10000m^{2}}$$

Roinn 50\pi \left(25+h\right) faoi 10000m^{2}.

$$c=\frac{\pi \left(h+25\right)}{200m^{2}}$$

Réitigh do c.

Céimeanna chun Cothromóidí Líneacha a Réiteach

Ríomh cumhacht 25 de 2 agus faigh 625.

$$10000cm^{2}=2\pi \times 625+2\pi \times 25h$$

Méadaigh 2 agus 625 chun 1250 a fháil.

$$10000cm^{2}=1250\pi +2\pi \times 25h$$

Méadaigh 2 agus 25 chun 50 a fháil.

$$10000cm^{2}=1250\pi +50\pi h$$

Tá an chothromóid i bhfoirm chaighdeánach.

$$10000m^{2}c=50\pi h+1250\pi$$

Roinn an dá thaobh faoi 10000m^{2}.

$$\frac{10000m^{2}c}{10000m^{2}}=\frac{50\pi \left(h+25\right)}{10000m^{2}}$$

Má roinntear é faoi 10000m^{2} cuirtear an iolrúchán faoi 10000m^{2} ar ceal.

$$c=\frac{50\pi \left(h+25\right)}{10000m^{2}}$$

Roinn 50\pi \left(25+h\right) faoi 10000m^{2}.

$$c=\frac{\pi \left(h+25\right)}{200m^{2}}$$

Réitigh do h.

$$h=\frac{200cm^{2}}{\pi }-25$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Ríomh cumhacht 25 de 2 agus faigh 625.

$$10000cm^{2}=2\pi \times 625+2\pi \times 25h$$

Méadaigh 2 agus 625 chun 1250 a fháil.

$$10000cm^{2}=1250\pi +2\pi \times 25h$$

Méadaigh 2 agus 25 chun 50 a fháil.

$$10000cm^{2}=1250\pi +50\pi h$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$1250\pi +50\pi h=10000cm^{2}$$

Bain 1250\pi ón dá thaobh.

$$50\pi h=10000cm^{2}-1250\pi$$

Roinn an dá thaobh faoi 50\pi .

$$\frac{50\pi h}{50\pi }=\frac{10000cm^{2}-1250\pi }{50\pi }$$

Má roinntear é faoi 50\pi cuirtear an iolrúchán faoi 50\pi ar ceal.

$$h=\frac{10000cm^{2}-1250\pi }{50\pi }$$

Roinn 10000cm^{2}-1250\pi faoi 50\pi .
