Answer:
Step-by-step explanation:
Solution: Radius = 7 cm
Height of cylindrical portion =13–7=6 cm
Curved surface are of cylindrical portion can be calculated as follows:
= 2 π r h
= 2 × 22/ 7 × 7 × 6 = 264 c m 2
Curved surface area of hemispherical portion can be calculated as follows:
=2πrh
=2×22/7×7×7=308 cm2
Total surface area
=308+264=572 sq cm
