उत्तर
In the given problem, we have to find the total surface area of a hemisphere of a given radius.
Radius of the hemisphere (r) = 10 cm
So, total surface area of the hemisphere = `3pi r^2`
`=3(22/7)(10)^2`
= 942.86 cm2
Therefore, the total surface area of the given hemisphere of radius 10 cm is 942.86 cm2.
