What is percentage error in sphere?
Volume of the sphere is V=43πr3. As per the rule for combination of errors for exponents ΔVV=3Δrr. =3 x 0.015. ΔVV=0.045. Percentage error =ΔVV×100=0.045×100=4.5%
What is the error in volume?
To calculate the error of a volume, the error for each cell of the volume has to be computed first. The altitude (Z) of a 3D point is computed with an accuracy of 1 to 3 times the ground sample distance (GSD). The average error for the height of each 3D point is 1.5 times the GSD.
What is the percentage error in volume?
Given, percentage error in its each side = 12% or △aa×100=12% Volume of cube, V=a3. Percentage error in volume of the cube is. △VV×100=3(△aa×100)=3×12%=36%.
How do you find the percentage of a surface area?
Calculate percentages by dividing the fraction’s numerator by its denominator, as in 16/64 = 16 divided by 64, or 1/4, or . 25 or 25 percent (%). Find the percentage of a portion of an object by dividing the area of the portion by the area of the whole original object.
How do you solve impervious surface area?
Calculation of Impervious Surface: Percentage of impervious surface shall be calculated by dividing the surface area of existing and proposed impervious surfaces on the portion of a lot or parcel that is within 300 feet of the ordinary high water mark by the total surface area of that portion of the lot or parcel that …
How do you find the total surface area of a rectangular prism?
The surface area of a rectangular prism calculator gives us the answer: A = 2 * l * w + 2 * l * h + 2 * w * h = 2 * 8 ft * 6 ft + 2 * 8 ft * 5 ft + 2 * 6 ft * 5 ft = 236 ft² . But that is the surface area of the entire prism, and we don’t want to tile it all around.
What is the surface area of a prism?
The lateral surface area of a prism is the sum of the areas of its lateral faces. The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Usually, if “right” or “oblique” is not mentioned, you can assume the prism is a right prism.
What is the relationship between the surface area of a rectangular prism and the area of each face?
1 Expert Answer. The surface area is the sum of the areas of each face.
What is the relationship between area and surface area?
The area is the measurement of the size of flat-surface in a plane (two-dimensional), whereas surface area is the measurement of the exposed surface of a solid shape (three-dimensional). This is the key difference between area and surface area.
What is the formula for the total surface area of a prism?
The general formula for the total surface area of a right prism is T. S. A. =ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
What is the surface area of this triangular pyramid?
Hence, the surface area of a triangular pyramid is 140 square units.
What is total surface area of pyramid?
The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces. The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. =12pl where p represents the perimeter of the base and l the slant height. …
What is the surface area of this rectangular pyramid?
The formula for the total surface area of a rectangular pyramid is calculated by adding up the area of all rectangular and triangular faces of a prism. which is T.S.A. = lw + l √(w2)2+h2+w√(l2)2+h2 ( w 2 ) 2 + h 2 + w ( l 2 ) 2 + h 2 . l = Length of the rectangular base.
