Question

The total surface area of hemisphere of radius 8 cm is​

Answer 1

Answer:

TSA of hemisphere =3πr^2

Step-by-step explanation:

=3*22/7*8*8

=4224/7

=603.42cm^2

Answer 2

The total surface area of hemisphere of radius 8 cm = 603.4 $cm^{2}$

Step-by-step explanation:

Given,

The radius of hemisphere (r) = 8 cm

To find, the total surface area of hemisphere of radius 8 cm = ?

We know that,

The total surface area of hemisphere = $3\pi r^2$

= $3\times \dfrac{22}{7}\times 8^2$

= $3\times \dfrac{22}{7}\times 64$

= 192 × 3.14857 $cm^{2}$

= 603.4 $cm^{2}$

∴ The total surface area of hemisphere of radius 8 cm = 603.4 $cm^{2}$

Thus, the total surface area of hemisphere of radius 8 cm = 603.4 $cm^{2}$
