Step-by-step explanation:
total surface area of cylinder = 2πr(r+h)
2×22/7×23 ×(23+27)
2×22/7 ×23 ×49
2×22×23×7
7084
total surface area of hemisphere = 3πr^2
3×22/7× 35×35
3×22×175
11550
their are 3 hemisphere = 3× 11550
34650
area of solid figure = area of cylinder + area of hemisphere
7084 + 34650
41734
