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.
Use this formula: V = radius2 x Pi x height
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
pi*radius2*height = volume of a cylinder height = volume divided by pi*radius2
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).
pi*r2*height = volume Make the height the subject of the above formula:- height = volume/(pi*r2)
yes
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.
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
Use this formula: V = radius2 x Pi x height
Volume = (Pi/4) * diameter2 * height or volume = Pi * radius2 * height
pi*radius2*height = volume Make the height the subject of the above formula:- height = volume/pi*radius2
pi*radius2*height = volume of a cylinder height = volume divided by pi*radius2
pi*radius2*height = 433.32 cubic centimeters pi*36*height = 433.32 Divide both sides by pi*36 to find the height: height = 3.831389997 cm
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).
pi*r2*height = volume Make the height the subject of the above formula:- height = volume/(pi*r2)
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
