picture a sphere. the surface area of a sphere is 4*pi*r^2.

now, cut it in half. the surface area is 4*pi*r^2 / 2 =2*pi*r^2

this is without including the bottom circular base

What is the difference between curved surface area of hemisphere and total surface area of hemisphere?

Curved surface area of a hemisphere means only the bent part of it , i.e,the part which looks like half of a sphere. Total surface area of a hemisphere is the circular top of a hemisphere + curved surface area of a hemisphere. So the formula goes like this: Curved surface area of hemisphere= 2πr2 Total surface area of hemisphere= 2πr2 + πr2 = 3πr2


How do you find the surface area of a hemisphere?

To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.


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 answer for the hemisphere?

The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².


What is the surface area of a closed hemisphere with a volume of 36pi?

Which has more land area - the northern or southern hemisphere?

The northern hemisphere has more land area compared to the southern hemisphere. About 68.3% of the Earth's land area is located in the northern hemisphere.


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.


What is the volume and area of hemisphere?

Volume = 2/3πr3 Surface area = 3πr2
