Answer:
= 3014.4 sq.cm.
Step-by-step explanation:
Fistly we have to find l (slant height)
formula l^2 = h^2 + r^2
= (32)^2 + (24)^2
= 1024 + 576
= 1600
l^2 = 1600
l = 40
Formula To Calculate curved surface area of cone is πrl
= 3.14 × 24 × 40
= 75.36 × 40
= 3014.4 sq.cm.
Finally, The curved surface area is 3014.4 sq.cm.

Answer:
l² = r² + h²
l² = (24)² + (32)²
l² = 576 + 1024
l² = 589824
l² = (768)²
l = 768 cm
curved surface area of cone = πrl
= 3.14 × 24 × 768
= 57876.48 cm²
