Question

Find curve surface area of cone if radius and slant height is 7cm and 10cm respectively​

Answer 1

Answer:

Step-by-step explanation:

Radius of cone (r) = 7cm

Slant height of cone (l) = 10cm

CSA of a cone = $\pi$rl sq.units

                        = $\frac{22}{7}$ × 7 × 10

                        = 220 cm²

∴ CSA of a cone with 7cm radius and 10cm slant height is 220 cm²
