Explanation:

Given: r1 = 1 cm, r2 = 2.5 cm, h =(7-1)= 6 cm

l = √(h² + (r2-r1)²)

= √((6)² + (2.5-1)²) cm

= √(36 + 2.25 )cm

= √38.25 cm

= 6.18cm

So,

External Surface area = (curved surface area of frustum) + (curved surface area of hemisphere)

= (22/7)(r1+r2)l +(2)(22/7)(r1)

= (22/7) [(1+2.5)6.18 + 2×(1)²] cm²

= (22/7)(3.5 × 6.18 +2) cm²

= (22/7) (21.63+2) cm²

= (22/7) × 23.63 cm²

= 519.86/7 cm²

= 74.26 cm²
