How do you find the volume of a trapezoid?
Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.
What is the volume of this cone use π ≈ 3.14 and round your answer to the nearest hundredth?
A cone has a volume of 461.58 cubic centimeters and a radius of 7 centimeters. What is its height? Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth….Time. Time.
How do you find the volume of a circular section?
The area of one end can be calculated using the formula for the area of a circle πr2. The diameter is 2cm, so the radius is 1cm. The area is therefore π × 12, which is 3.14cm2. The length of the pipe is 1.7m, so you need to multiply the end area by the length in order to find the volume.
How do you find the volume of a tapered cylinder?
The formula for the volume of a conical cylinder is given as, V = πH/3 (R2 + Rr + r2) where “V”, “H”, “R” and “r” are volume, height, larger base radius, and smaller base radius of the conical cylinder.
What is the volume of this sphere use π ≈ 3.14 and round your answer to the nearest hundredth 7 ft cubic feet?
about 4.19 cubic feet
Use 𝜋 ≈ 3.14. The volume of the sphere is about 4.19 cubic feet.
How do you use pi to round to the nearest hundredth?
To round to the nearest hundredth, we therefore need to look at the digit immediately to its right—in other words, the 1 in the thousandths place. Since that number is less than 5, we need to round down—which gives us a rounded value of pi equal to 3.14.
Does circle have volume?
No, a circle doesn’t have a volume. A circle is a two-dimensional shape, it does not have volume. A circle only has an area and perimeter/circumference.
Does a baseball have volume?
According to The Physics Factbook online, the standard diameter for a baseball is about 7.3 centimeters. The radius would be 3.65 centimeters. Find the volume of the baseball by using the formula 1.33 times pi times the radius cubed. Multiply 4.1762 times 48.627 to get a volume of 203.076 cubic centimeters.
How do you calculate frustum?
There are two formulas that are used to calculate the volume of a frustum of a cone. Consider a frustum of radii ‘R’ and ‘r’, and height ‘H’ which is formed by a cone of base radius ‘R’ and height ‘H + h’. Its volume (V) can be calculated by using: V = πh/3 [ (R3 – r3) / r ] (OR)
How do we find the radius of a circle?
Let us use these formulas to find the radius of a circle.
- When the diameter is known, the formula for the radius of a circle is: Radius = Diameter / 2.
- When the circumference is known, the formula for the radius is: Radius = Circumference / 2π
What is the formula for the volume of a trapezoid?
Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2.
How do you calculate the square footage of a trapezoid?
Trapezoid: In this case you need the top edge, bottom edge, left side, right side. The formula for a trapezoid is: Square footage Trapezoid= Height* (top edge + bottom edge)/2.
What is the volume of a trapezoid prism?
Thus, the volume of the prism is 70 cubic centimeters (cc). A trapezoidal prism has a length of 5 cm and bottom width of 11 cm. The top width is 6 cm, and slant height is 2 cm.
How do you find the surface area of a trapezoid?
Determining the surface area of a trapezoid is a bit more challenging. The area of a trapezoid can be expressed in the formula A = 1/2 (b1 + b2) h where A is the area, b1 is the length of the first parallel line and b2 is the length of the second, and h is the height of the trapezoid.
