How can you use pi to measure the height of an elephant?
An ocular way of estimating the height of an elephant is to measure the diameter of its foot and multiply it by 2pi - Mohd. Thayyab,Divisional Forest Officer, A.P., India.
How can you use pi to find the height of an elephant?
Pi is 3.14, a number that represents the ratio between a circle's circumference and its diameter. It cannot be used to find the height of an elephant.
What is the length of a cylinder if the volume is 210 liters and the diameter is 400mm?
V=Abase x height V= (pi)(radius)2height 210=(pi)(200)2height 210=(pi)(40000)height 210 --------------- = height (pi)(40000) 0.0016719= height. therefore the length (height) is 0.00161719, assuming we use 3.14 for pi.
How do you find the volume of a cylinder when you know the circumference and height?
Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).
How do you Calculate volume of a cylinder in cubic meters?
The volume of a cylinder equals (pi) x radius square x height where pi = 3.14
How can you solve a cylinder with 18 as a diameter and 18 as a height?
If you're looking for the volume of the cylinder, use the formula:Area*height = (pi*radius2)*heightto find the radius you just divide the diameter by 2.Using your values:Volume=[pi*(18/2)2] * 18 = 1458*pi = 4580.44If you're looking for the surface area, use the formula:Surface Area = circumference*height + 2(Flat area) = pi*diameter*height + 2(pi*radius2)Using your values:Surface Area = pi*18*18+2[pi*(18/2)2] = 324*pi + 2*1458*pi = 3240*pi = 10179
How do you find the height of a cylinder if the surface area is 312 inches and the radius is 2 inches?
Entire surface area = (2*pi*4)+(4*pi*height) = 312 (4*pi*height) = 312-(2*pi*4) (4*pi*height) = 286.8672588 Divide both sides by 4*pi to find the height:- height = 22,82817112 inches Check: (2*pi*4)+(4*pi*22.82817112) = 312 square inches Formula: (2*pi*radius2)+(diameter*pi*height) = area
How do you get circumference for the circle?
Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.
What is the formula for the volume of a cylinder?
The volume of a cylinder is simply the area of the circular base times the cylinder's height. Volume of a cylinder = ╥ r² h (pi x radius squared x height) ╥ (Pi) ≈ 3.14 r = radius of the base circle, and h = height of the cylinder --- V= pi r squared times height Volume in cubic units = pi*radius2*height
How do you calculate the volume of a washer?
The formula for the volume of a cylinder is pi times the radius squared times the height. Pir^2h
How do you find the volume of a circular prism?
you do the area of the base (circle - pi*radius squared) times the height (measure the tubular face).
What is the volume of a cylinder with a radius of 11?
You also need the height. Use the formula volume = pi x radius2 x height.
