Question

Find the curved surface area of a cone of radius 7cm and height 24cm

Answer 1

Hiii friend,


Radius = 7 cm

And,


Height = 24 cm


Slant Height (L) = ✓(R)² + (H)² = ✓(7)² + (24)² = ✓49 + 576 = ✓625 = 25 cm


Therefore,



CSA of cone = πRL = 22/7 × 7 × 25 = 22 × 25 = 550 cm².



HOPE IT WILL HELP YOU...... :-)

Answer 2

hlo ...

here the ans is...

given: r=7cm
           h=24cm

l²=r²+h²
l²=7²+24²
l²=49+576
l²=625
l=√625
l=25

CSA of cone =22/7×7×25
                      22×25
                       550

∴the CSA of cone is 550 cm²

hope my ans u dear....
                ^-^
plz..make my ans as brainliest if i deserve..
