Question

find the curved surface area and total surface area of the cylinder whose dimension is radius of the base = 14m and height = 15m​

Answer 1

CSA of cylinder=2πrh
=2×22/7×14×15
=2×22×2×15
=1320cm²

Answer 2

$C.S.A = 2πrh \\ </p><p> =2×22/7×14×15 \\ </p><p> =1320 {m}^{2} \\ t \:.s.a. = 2\pi \: r(r + h) \\ =\ 2 \times 22 \div7 \times 14(14 + 15) \\ = 1672 {m}^{2} </p><p>$
