To find the diameter of a star, scientists use a method called interferometry. This involves combining data from multiple telescopes to create a detailed image of the star's surface. By measuring the angular size of the star and its distance from Earth, astronomers can calculate its diameter.

How do you calculate diameter of a oil tank?

To calculate the diameter of a cylindrical oil tank, you can use the formula: diameter = 2 * square root of (volume / (pi * height)), where the volume and height of the tank are known. Input these values into the formula to find the diameter.


How Can you find the volume of an inflated balloon?

To find the volume of an inflated balloon, you can measure its diameter using a ruler and then use the formula for the volume of a sphere, V = (4/3) * pi * r^3, where r is the radius (half of the diameter) of the balloon. Plug in the radius and calculate the volume. Alternatively, you can submerge the inflated balloon in a container of water and measure the water displacement to find the volume of the balloon.


How to find the mass of a star using observational data and theoretical models?

To find the mass of a star using observational data and theoretical models, scientists analyze the star's brightness, temperature, and spectral characteristics. By comparing these observations to theoretical models of stellar evolution, they can estimate the star's mass. This process involves complex calculations and may require data from multiple sources, such as telescopes and computer simulations.

What is the relationship between the diameter and area of a piston?

Area of a circle is pi*(radius)². Pi is a dimensionless constant (approximately 3.14). Radius is 1/2 of the diameter, so if you replace radius with diameter/2, then you get (3.14)*(dia/2)² = (3.14/4)*(dia)², or approx. (0.785)*(diameter)²
