it is 3 times pi times r square, where r is the radius.
what is the formula to finding the total surface area of a rhomboid?!
Total surface area = 1847.26 sq cm.
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
Surface area is the total space that a three-dimensional object occupies. When using the mathematical formula for its shape you get the surface area measurement.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
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
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.
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.
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.
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.
what is the formula to finding the total surface area of a rhomboid?!
total curved surface area = 2*pie*r^2
3*pi*r2
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
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.
The curved surface area is 89.76527 units2 and the total surface area is 134.6479 units2
it stands for the total surface area
