Question

Find the total surface area of a cylinder with radius 13.3cm and height 10.5cm respectively

Answer 1

Answer:

Explanation:

2pir(h+r)

2×22÷7×13.3×(10.5+13.3)

2×22×1.7×23.8

44×1.7×23.8

44×40.46

1780.24

PLEASE MARK BRAINLIEST

I DID A LOT OF CALCULATION WITHOUT CALCULATER A LOT OF HARD WORK

Answer 2

$\huge\mathbb{SOLUTION:-}$

$\sf\underline{\blue{\:\:\:\:\:\:\:\: Given:-\:\:\:\:\:\:\:\:}}$

$\sf\:\:\:\: \bullet radius\:of\: cylinder=13.3cm\\ \\ \sf\:\:\:\: \bullet height\:of\: cylinder=10.5cm$

We have to find the T.S.A of cylinder

$\underline{\purple{\star{\sf{T.S.A\:of\: cylinder=2\pi r(h+r)}}}}$

$\sf:\leadsto T.S.A=2\times \dfrac{22}{\cancel7}\times \cancel{13.3}(13.3+10.5)\\ \\ \sf:\leadsto T.S.A=2\times 22\times 1.9\times 23.8\\ \\ \sf:\leadsto T.S.A= 44\times 33.25\\ \\ \sf:\leadsto T.S.A=1463cm{}^{2}$

$\boxed{\sf{\red{T.S.A\:of\: cylinder=1463cm{}^{2}}}}$
