Answer 2

Given :-

Radius of the top of bucket = 15 cm

Radius of the bottom of bucket = 5 cm

Height of the bucket = 24 cm.

To Find :-

Surface area of the bucket.

Solution :-

Here the bucket is in shape of a frustum.Let us find the slant height first!

$\sf\red{:\implies Slant\: Height= \sqrt{(R-r)^2+h^2}}$

$\implies\sf Slant\: Height_{Bucket}= \sqrt{15-5)^2+(24)^2}$

$\implies\sf Slant\: Height_{Bucket}= \sqrt{(10)^2+(24)^2}$

$\implies\sf Slant\: Height_{Bucket}= \sqrt{100+576}$

$\implies\sf Slant\: Height_{Bucket}= \sqrt{676}$

$\implies{\boxed{\pink{\sf\ Slant\: Height_{Bucket}= 26 cm}}}$

$\therefore\:\underline{\textsf{Slant height of the bucket is \textbf{26 cm }}}$

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

$\red{\implies\sf\ S.A= π\times (R+r)\times l}$

$\implies\sf\ S.A_{Bucket}= 3.14\times (15+5)\times 26$

$\implies\sf\ S.A_{Bucket}=81.64\times 20$

$\implies\sf\ S.A_{Bucket}= 1634.28$

$\implies{\boxed{\pink{\sf\ Surface\ Area_{Bucket}= 1634.28 cm^2}}}$

$\therefore\:\underline{\textsf{Surface area of the bucket is \textbf{ 1634.28 cm²}}}$
