Total surface area = 1847.26 sq cm.

it is 3 times pi times r square, where r is the radius.

The total surface area of a sphere when the radius is 4 equals 201.1 units2

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.

Total surface area = 1847.26 sq cm.

it is 3 times pi times r square, where r is the radius.

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.

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 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.
