Question

what is LSA of hemisphere
and volume​

Answer 1

Answer:

CSA = 2πr2. The curved surface area of a hemisphere = 2πr2 square units. The total surface area of the sphere = Curved surface area of sphere + base area. We know that the base of the hemisphere is circular in shape, use the area of the circle. TSA = 2πr2 + πr2 = 3πr2.

Answer 2

$\large \tt \pink {answer}$

LATERAL SURFACE AREA OF A HEMISPHERE IS 2PIEr^2.
