A hemisphere is half of a sphere. The volume can be found by calculating the volume of the whole sphere and dividing by 2 or by halving the formula: Volume of hemisphere = 2 3 π r 3 The surface ...

The total surface area of the cylinder is two circle areas, 2 × π𝒓², plus the curved surface area of the rectangle, 2π𝒓 × 𝒉. This gives the formula, surface area = 2π𝒓² ...

Surface Area and Volume Solved Examples Que 1: Find the lateral surface area of a cylinder with a base radius of 10 cm and height 20 cm. Solution: Given radius r = 10, height h = 20 LSA = 2 π rh ...

KnowHOW team explains: Water drops, or, for that matter, the drops of any other liquid, are spherical in shape due to a phenomenon called surface tension. In a liquid this acts on the surface of a ...

A strange scaly circle on the surface of Mars has become the subject of much speculation for scientists. Reported by the Daily Mail, NASA is currently investigating a strange mark on the South ...
