The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
The curved surface area of a cylinder whose height is 14 feet and radius is 6 feet is 527.79ft2
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
Shape of capsule: A circular cylinder with hemispheres mounted on both sides. Radius of each hemisphere is equal to the radius of cylinder. Let the length of the cylinder be h. Surface area of capsule = Curved surface area of cylinder + Curved Surface area of two hemispheres Surface area of capsule = 2 x pi x r x h + 2 x 2 x pi x r x r = 2 x pi x r x (h+2r)
If the diameter is 25 then the radius must be 12.5
If cylinder radius and cylinder length are known : (pi = 3.141592654 . . . ) > Surface area = ( (2 * pi * radius) * length )
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
The lateral surface area is 8796.46cm2
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
A cylinder's length is 12 inches, and its radius is 6 inches. What is the surface area of the cylinder to the nearest tenth ?
2 x Pi x radius x height or length = curved surface area
Surface area of a hollow cylinder = 2*pi*radius*length measured in square units.
The height of a cylinder with the radius of 7 and surface area of 550 is 5.51
The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
The surface area of a cylinder with a radius of 6ft and a height of 7ft is 490.09ft2
The height of a cylinder with a radius of 8 and a surface area of 954.56 is 10.99
The surface area of a cylinder with a radius of 3.8cm and a height of 11cm is 353.37cm2
