Determine the volume of a cone with a curved surface area of 180 cm² and a radius of 6 cm. (Assume π = 3 for calculations.)
Let the slant height of the cone be ‘l’ cm. Curved surface area of the cone = π × r × l = 180 3 × 6 × I = 180 I = 10 cm Let height of the cone be ‘h’ cm. According to Pythagoras theorem: r2 + h2 = l2 62 + h2 = 102 h2 = 100 – 36 h = √64 = 8 So the volume of the cone = 1/3 × π × r2 × h = 1/3 × 3 × 36 × 8 = 288 cm2
