The diameter of a solid hemisphere is 10 cm. Find its total surface area (use π = 3.14).

288 cm2 265.8 cm2 235.5 cm2 245 cm2

235.5 cm2

We know that, Total surface area of hemisphere = 3πr2 Diameter of solid hemisphere = 10 cm. Then radius = 5cm Total surface area of hemisphere, = 3 × (3.14) × 52 = 3 × (3.14) × 25  = 235.5 cm2
