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.
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.
What are the properties of a hemisphere?
A hemisphere is a three-dimensional shape that consists of a half-sphere. It has a curved surface and a flat base. The formula for the volume of a hemisphere is V = (2/3)πr^3 and for the surface area is A = 3πr^2.
Is the north hemisphere bigger than the south hemisphere?
No, the north hemisphere is not bigger than the south hemisphere. The Earth's hemispheres are divided equally by the equator, so each hemisphere covers half of the Earth's surface area.
How big is the western hemisphere?
The western hemisphere covers approximately half of the Earth's surface, stretching from the Prime Meridian to the International Date Line. It includes North and South America, the western part of Europe, and the western half of Africa. The area of the western hemisphere is about 20.3% of the Earth's total land area.
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 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 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 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 5.5 feet?
Surface Area = ~285.1 ft2
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.
What is the volume and area of hemisphere?
Volume = 2/3πr3 Surface area = 3πr2
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.
What is the surface area in square centimeters of a hemisphere that has a radius of 14 centimeters?
Total surface area = 1847.26 sq cm.
What is the total curved surface area of a hollow hemisphere?
total curved surface area = 2*pie*r^2
