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.
No, the volume formula is not universal for all figures. Different shapes and objects have different formulas to calculate their volume based on their unique dimensions and properties. Each shape requires its own specific formula to accurately determine its volume.
To find the volume of a cylinder, use the formula V = πr^2h, where r is the radius of the cylinder and h is the height. Measure the radius and height of the cylinder and plug them into the formula to calculate the volume.
The volume of a cylinder is volume=((Pi)*radius^2)*height. Therefore it is equal to 1^2*pi=pi times height(18) =18pi cm cubed
To measure the area of a rough surface, you can use a paper method: cover the surface with graph or tracing paper and trace the outline, then count the squares to determine the area. Another method is to use a digital imaging software to capture an image of the surface and measure the area digitally.
The volume of the ball, right? You can measure the ball's diameter, divide by 2 to get the radius, then use the formula for the volume of a sphere. If you find it difficult to measure the diameter, you can also measure the circunference, and divide that by (2 x pi) to get the radius.
