Question

the diameter of cone is 14 cm and it's slant height is 9cm.Find it's CSA​

Answer 1

Answer:

198 $cm^{2}$

Step-by-step explanation:

CSA of cone = πrl

where r = 7cm (d = 14cm)

l = slant height = 9cm

∴CSA = $\frac{22}{7}$ × 7 × 9

= 22 × 9

= 198 $cm^{2}$

∴ CSA of the cone is 198 $cm^{2}$

I hope this is correct :)
