What is the surface area of a closed hemisphere with a volume of 36pi?
The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
Which one of the following geometric forms is a curved surface?
A sphere has a total curved surface. A cylinder and a cone have a partial curved surface
What is the formula for calculating surface area of a hemisphere?
The surface area of a whole sphere, of radius r, is 4*pi*r2.The area of the curved surface of a hemisphere is, therefore, 2*pi*r2.The area of the flat surface is that of a circle of radius r, that is = pi*r2.So the total surface area of a hemisphere is 2*pi*r2 + pi*r2 = 3*pi*r2.
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
Find the surface area of a hemisphere with a radious of 3?
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
