Curved surface area of a cone = pi*radiud*length of slant
width times height
it is 2(lw)+2(wh)+2(hl)
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
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!
The suface area of a cylinder with a radius of 8 and a height of 14 is 1,105.84 units2
1/3Ah That is to say, 1/3 times the area of the base times the height (not the slant height) of the cylinder
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
(h is the height of the cylinder, r is the radius of the top)Surface Area = Areas of top and bottom +Area of the sideSurface Area = 2(Area of top) + (perimeter of top)* heightSurface Area = 2(pi r 2) + (2 pi r)* hcredit to:http://www.math.com/tables/geometry/surfareas.htm#cylinder
The suface are of a rectangular prism is the area of each face added together for a total.
The suface area of a sphere with a radius of 7 meters is 615.75m2
Entire suface area: (2*pi*4.52)+(9*pi*12.5) = 480.664 square units rounded to 3 dp
Surface area of a sphere = 4πr2
Entire suface area = (2*pi*42)+(8*pi*40) = 1105.841 sq ins rounded to 3dp
Their roots and their suface area
its in geelong so suck on that
Curved surface area of a cone = pi*radiud*length of slant
