Answer 1

Given, the curved surface area of a cylindrical road is 132 cm².

☯we need to find it's height.

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

We know that,

⠀

$\star\;{\boxed{\sf{\purple{CSA_{(cylinder)} = 2\pi \: r \: h }}}}$

Putting values,

$:\implies\sf 132 = 2 \times 3.14 \times 0.35 \times h$

$:\implies\sf 132 = 6.28 \times 0.35 \times h$

$:\implies\sf 132 = 2.198 \times h$

$:\implies\sf h=\cancel\frac{132}{2.198}$

$:\implies{\boxed{\frak{\pink{h = 60 cm }}}}\;\bigstar$

$\therefore\;{\underline{\sf{Hence,\;Height\;of\;the\;cylindrical \; rode\; is\:\bf{60\;cm}.}}}$
