What is the surface area of sphere with radious of 3.5?
Surface area of a sphere = 4*pi*radius2 Area = 49*pi square units
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.
Surface area of a closed circular cylinder with 10 as the radious and 9 as the height?
The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
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
