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
