Find the Lateral surface area of the frustum, if the slant height is 12 cm and having radii as 15 cm and 35 cm.
Find the Lateral surface area of the frustum, if the slant height is 12 cm and having radii as 15 cm and 35 cm. Correct Answer 1884 cm2
s = 12 cm, R = 35 cm, r = 15 cm Lateral Surface area of frustum = π(r + R)s L = 3.14 × (15 + 35) × 12 = 1884 cm2
