The diameter of a solid hemisphere is 35 cm. What is its total surface area? (Take $π =\frac{22}{7}$)

2887.5 cm²

We know that,

Total Surface area of the hemisphere = 3πr².

We have,

Diameter of the solid hemisphere = 35 cm.

Then the radius = \(\frac{35}{2}\)

T.S.A of the hemisphere = 3 × \(\frac{22}{7}\) × (\(\frac{35}{2}\))² = 2887.5 cm²
