One method would be to measure the elephant's shadow and the shadow of a known object with a known height, then use the ratio of the two shadows to determine the elephant's height. Pi comes into play when calculating the angle of the sun's rays hitting the objects to account for the height difference.
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.
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.
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).
The volume of a cylinder equals (pi) x radius square x height where pi = 3.14
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
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
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.
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
The formula for the volume of a cylinder is pi times the radius squared times the height. Pir^2h
To find the capacity (volume) of a cone, you can use the formula ( V = \frac{1}{3} \pi r^2 h ), where ( V ) is the volume, ( r ) is the radius of the base, and ( h ) is the height of the cone. First, measure the radius and height, then substitute these values into the formula. Calculate the area of the base using ( \pi r^2 ), multiply it by the height, and finally divide by 3 to get the volume.
You also need the height. Use the formula volume = pi x radius2 x height.
