Answer 2

$\sf{Answer}$

Step-by-step-explanation:-

Given :-

• Radius of cylinder 8cm
• Height of cylinder 12cm

To find :-

T.S.A of Cone

Formula implemented:-

TSA of cone = πr(r+l)

l= $\sqrt{h²+r²}$

Solution:-

Radius of cylinder 8cm

Height of cylinder 12cm

Slant height of cone = $\sqrt{h²+r²}$

Slant height = $\sqrt{8²+12²}$

Slant height = $\sqrt{208}$

TSA Of cone = 22/7× 8(8+$\sqrt{208}$

TSA of cone = 563.53cm²
