How do you find the total surface area of a hemisphere whose diameter is 8 inches?
Calculate the radius (it is half the diameter).Use the formula for a sphere: area = 4 x pi x radius2.Since a hemisphere is half a sphere, divide this result by 2.Question:Do you mean the surface area to include the flat face of the hemisphere?If so then follow the above instructions and add pi*42 to your answer which will give you the complete surface area of the hemisphere.
What is half of the sphere that makes up earths surface?
hemisphere.
What 3D shape has 1 circular face and one which is half the surface of a sphere?
A hemisphere has 1 circular face and one which is half the surface of a sphere.
Name of half of a sphere?
a half-sphere is called "hemisphere"
What is the surface area of a hemisphere?
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^2this is without including the bottom circular base
How do you find the surface area of a hemisphere?
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π r2.
What is half of the earths surface called?
A hemisphere is one half of the sphere that makes up Earth's surface.
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

What is half of Earth's surface?
A hemisphere is one half of the sphere that makes up Earth's surface.
What is half of the sphere that makes up earths surface?
hemisphere.
Is a hemisphere a half of sphere or a whole sphere?
A hemisphere is a half sphere
What 3D shape has 1 circular face and one which is half the surface of a sphere?
A hemisphere has 1 circular face and one which is half the surface of a sphere.
What shape has 1 circular face which is half the surface of a sphere?
It is a hemisphere.
Name of half of a sphere?
a half-sphere is called "hemisphere"
What is the surface area of a half-sphere with a radius of 10?
Surface area of half a sphere = 2*pi*radius2 Surface area = 200*pi = 628.3185307 square units.
What is radius of hemisphere whose total surface area is 942 cm?
The surface area of a sphere can be found with the formula 4pi * r2. Assuming the hemisphere is exactly half of a sphere, the surface area of a hemisphere can be found using the formula A = 2pi * r2 + pi * r2 Which can be written as A = pi(3r2) 942cm/pi = 3r2 314cm/pi = r2 r = 10cm (approximately) The radius of the hemisphere is approximately 10cm.
