find find the curved surface area of the solid hemisphere whose diameter is
Answers
Curved Surface Area of Solid Hemisphere = 2πr²
where π = 22/7 and r = radius
i) given diameter = 9.8 cm
radius = r = 9.8/2 = 4.9
Curved Surface Area of Solid Hemisphere = 2 × π × (4.9)²
= 2 × 22/7 × 49/10 × 49/10 = 150.92 cm²
ii) given diameter = 18.2 cm
radius = r = 18.2/2 = 9.1 cm
Curved Surface Area of Solid Hemisphere = 2 × π × (9.1)²
= 2 × 22/7 × 91/10 × 91/10 = 520.52 cm²
iii) given diameter = 70 cm
radius = r = 70/2 = 35 cm
Curved Surface Area of Solid Hemisphere = 2 × π × (35)²
= 2 × 22/7 × 35 × 35 = 7700 cm²
iii) given diameter = 70 cm
radius = r = 70/2 = 35 cm
Curved Surface Area of Solid Hemisphere = 2 × π × (35)²
= 2 × 22/7 × 35 × 35 = 7700 cm²
iv) given diameter = 1.4 m
radius = r = 1.4/2 = 0.7m
Curved Surface Area of Solid Hemisphere = 2 × π × (0.7)²
= 2 × 22/7 × 7/10 × 7/10 = 3.08 m²
