Question

find tsa of cylinder whose radius is equal to 7m and height is equal to 21m

Answer 1

Hiii!!!

here's ur answer...

given radius is 7m and height is 21m

TSA of the cylinder=2πr(h+r)

=2×22/7×7(21+7)

=44×28

=1232m²

hope this helps...

Answer 2

TSA of cylinder
$= 2 \times \pi \times r(h + r)$
$= 2 \times\pi \times 7(21 + 7)$
$= 2 \times \pi \times 7(28)$
$= 2 \times 22 \div 7 \times 7(28)$
$= 2 \times 22 \times 28$

$= 1232 {m}^{2}$
