Kimvua kinataka either faru john au blanket chapa mtu mama😅

Sijui nitupie kapicha!?😂

Tupia mkuu, sisi wengine faru John mara moja sana, option ya pili ndio yenyewe😅

 

[Chamoto]

Sasa ulikate la kazi gani 😁😁 unaweza kulikata ukapata hata ramani ya tanzania 😁😁

Hiyo kulikata/kulikunjuwa, unafanya kichwani ili unapata formular hii ya surface area of a cylinder = 2πr(h+r) (where r is the radius and h is the height).

Hahahaha.. Mimi nilikuwa ticha wa Grade A

Wengine hatukumaliza hata o level

Umekosea ni 2πr(h) tu

Hiyo ni lateral surface area of a cylinder, excluding the circles.

3x + 2x = 120
5x = 120
X = 24

Yupo sahihi mkuu

4√2-3√2
√2

 

[Lwiva]

Yupo sahihi mkuu

πr ni nusu mzunguko wa duara hivyo kupata mzunguko wote unazidisha kwa 2 ndiyo hiyo 2πr
kisha unazidisha kwa kimo (h)
