# Find the total surface area of a hemisphere of radius 10 cm.

Q : 3    Find the total surface area of a hemisphere of radius 10 cm. (Use $\small \pi =3.14$)

Views

We know,

The total surface area of a hemisphere = Curved surface area of hemisphere + Area of the circular end

$= 2\pi r^2 + \pi r^2 = 3\pi r^2$

$\therefore$ The required total surface area of the hemisphere = $3\times3.14\times(10)^2$

$\\ = 942\ cm^2$
