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
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 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
What is the approximate surface area of a hemisphere shape with a radius of 27 feet?
Surface Area = ~6,870.7 ft2
Why isn't the surface of a hemisphere not half the surface area of a sphere?
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
