Question

Find curved surface area of cone if radius of base is 3 metre and height is 4 metre​

Answer 1

Step-by-step explanation:

Curved surface area of a cone = πrl, where l = √ (r2 + h2 ). Given r = 4 cm and h = 3 cm. l = √ (42 + 32 ) = 5 cm. Curved surface area of a cone = (22/ 7) x 4 x 5 = 62.85 cm2 .
