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.
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.
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.
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.
The diameter of a period on a typewriter is 3 mm.
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
The diameter of the Texas Star ferris wheel is 212 feet.
The diameter of the first Death Star, as depicted in Star Wars Episode IV: A New Hope was 160 kilometers. The second Death Star, which appeared in Star Wars Episode VI: Return of the Jedi, was significantly larger, with a diameter of 900 kilometers.
There are many types of Dwarf stars - all with different diameters. Our Sun is a dwarf star! A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
Our Sun has a diameter of about 109 times the diameter of the Earth or 1.392×106 kmThe Sun is a medium small star.
In that case, both the star's diameter and its luminosity greatly increase.
Diameter, I assume. That would be a neutron star.
Take the circumference divided by pi to find the diameter and divide the diameter by two to find the radius.
You multiply the diameter by pi (3.14) and u find the diameter
you double the radius to find the diameter.
