The diameter of an object is twice the radius. Therefore 1,737.4 * 2 = 3,474.8

How many peas would it take to reach the moon from earth?
First, you need to find the information you need to solve for the answer. A pea measures approximately 1 cm in diameter (from one point to the point on the opposite end). The distance from the center of the Earth to the center of the moon is about 384,467 km. If you subtract from this distance the average radius of the Earth (6,378 km) and the average radius of the moon (1,738 km), you find 376,351 km. Convert the diameter of a pea, 1 cm, to kilometers: .00001 km. Now, divide the distance from the surface of the Earth to the surface of the moon by the diameter of a pea. The answer is: 37,635,100,000 peas. That's about 5 times the population of the Earth, and about a third of the estimated number of stars in this galaxy!
Use the small-angle formula to find the angular diameter of mars when it is closest to Earth how does that compare with the maximum diameter of Jupiter?

How do you calculate a microscopes field of view?
Since the field of view is a circle, the size of the field of view is it's area. You would need to find the diameter of the field of view, using a transparent ruler or a micrometer. Divide the diameter measurement by 2 to get the radius. Then use the formula for the area of a circle, Area = πr2. For example, you measure the diameter of the field of view to be 2.14mm. Divide 2.14mm by 2 to get the radius, and you get 1.07mm. Square 1.07mm, which is 1.14mm2. Multiply x 3.14 (pi), and you get 3.58mm2. So the field of view for this example would be 3.58mm2.The field of view differs with different magnifications. The lower the magnification, the larger the field of view.
What an orbit is and what factors affect the size speed and time period of an orbit?
An orbit is the path followed by a planet according to Kepler's laws, which are very accurate but not exact. Size, speed and period are all related by simple formulas so that if you know one you can find out the other two. The orbit is an ellipse and the size is usually measured by its mean radius, also called its semi-major axis, which is the average of the maximum and minimum distances. For the Earth that is 149.6 million kilometres. The orbital period is proportional to the mean radius to the power 1.5, while the orbital speed is inversely proportional to the square root of the mean radius.
How much bigger sun to mars?
The Sun is 875,000 miles across, though scientists usually use AU which is Astronomical units or they would use kilometers. In which case it is 1,392,000 kilometers across/ wide and the radius of the Sun is about 700,000 km (435,000 miles). Mars has a diameter of 6,800 km or 4,200 miles across. The radius of mars is 3397 km at equator, 3375 km at pole. But if you want to find how much bigger it is than you can do some math and figure it out yourself and i bet your teacher will be very impressed too!
How can you use radius to find the diameter?
you double the radius to find the diameter.
How do you find diameter from radius?
diameter = 2*radius
What is the diameter of a circle if the radius is 27 cm?
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
How do you find the radius if the diameter is given?
the radius is half the diameter
How do you find radius when given a diameter?
The radius is half the diameter.
How do you find the radius of a circle from the diameter?
the radius is half the diameter
Can you find the diameter by doubling the radius?
Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
How do you find the diameter if you have the radius?
The diameter is twice the radius. So multiply the radius by 2
How to find radius?
The radius of a circle is half of the diameter. Radius= Diameter divided by 2
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How do you find the diameter of a circle when you know the radius?
Diameter = 2*Radius
How do you find a radius if the diameter is given?
divide diameter by 2 = radius
