Question

The radius of a solid hemisphere is 7cm. Find its total curved surface area.​

Answer 1

Answer:

TSA of the hemisphere = 3πr²

                                    = 3×22/7 ×7×7 = 462 cm²

hope this helped

Answer 2

Answer:

Radius = 7cm

Curved surface area of hemisphere =

$2\pi \: r {}^{2}$

= 2x 22/7 x 7x7

=

308

$cm { }^{2}$
