If the width of the roof is 26ft what is the total area of the roof?
Another dimension is needed to work out the surface area of the roof.
The lateral surface area of a right circular cylinder is 200 sq. ft . If the altitude is 8 ft. find the volume of the cylinder?
In order to calculate the volume we must work out the radius. Lateral surface area without the 2 end pieces of the cylinder = 200 sq.ft, 2*pi*r*8 = 200 Divide both sides by 2*pi*8 to find the length of the radius. radius = 3.978873577 Volume in cubic units = pi*radius2*height or altitude; Volume = 397.8873577 cubic feet or 398 to the nearest cubic foot.
How do you work out the surface area of a 3D shape?
take 1 face and times the base by height and the times it by the number of faces b * h = area of 1 face area of 1 face * number of faces = surface area note all faces must be the same! Hope i HELPED :D
How do you figure the square footage of a dome?
Tricky. You need to flatten out the surface to work it out. Depends on the shape - if it's like a hemisphere then you can use the properties of a sphere - volume = 4/3 Pi R3 and surface area = 4 Pi R2 so if your dome is like half a sphere then its surface area = 2 Pi R2 and you can measure the radius R so can work it out!
What is the formula to work out the surface area of a trapezoid?
the surface area of the trapezoid =(h/2)*(b1+b2) the unit is cm2 * * * * * Not particularly helpful when h, b1 and b2 are undefined. And not even true if these lengths are measured in inches!
