β 8y agoStand facing the moon. Hold your arm straight out holding the ruler horizontal and across your line of sight. Raise or lower the ruler stick so that the diameter of the moon is aligned with the straight edge. Using the pen, mark the apparent positions of the two ends of the diameter. Suppose the distance between then is x millimetres.
Measure the distance from your eye to the ruler stick = y mm.
Suppose the known diameter of the moon is m km.
Then, by similar triangles, x/y = m/d where the distance to the moon is d km. That is, d = (m*y/x) km.
It is best to use the same measurement unit for x and y, and for m and d. They can be Imperial or metric (or made up ones). That will avoid having to convert.

Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
a circle having a diameter of 1.4732 meters has an area of about 1.7 square meters.
If you have only the arc length then you cannot find the diameter.

In math, radius is the distance from the center of a circle to any point on the circle. It is half the diameter of a circle.

By the person's way of answering certain questions, or by listening to the person while having a conversation with him.... There is no other way of knowing people except by having conversations with them.
Knowing the distance and time the object traveled provides the necessary information to calculate the object's velocity. Velocity is defined as the rate of change of position with respect to time. By having both distance and time, one can determine how fast the object is moving and in what direction.

is the diameter of a sphere having same volume as that of the paricle.
The planet with the smaller diameter will have stronger gravity at its surface because gravity is dependent on the mass of the planet and the distance from its center. Having a smaller diameter means that you are closer to the center, resulting in stronger gravitational pull.
Knowing the distance from at least three recording stations helps triangulate the exact location of the epicenter of an earthquake. By having multiple points of reference, scientists can more accurately pinpoint the epicenter and determine the intensity and magnitude of the earthquake.δΈ

You don't need a mathematical equation. All you need are the numbers.In round, approximate numbers:-- Earth diameter = 12,750 km-- Moon diameter = 3,475 kmIf you want a 'ratio' to amaze your friends with, then you can use an actualmathematical equation for that:The ratio of the Earth's diameter to the Moon's diameter isDE / DM = 3.669 (rounded)-- The linear dimensions of the Earth are 3.669 times as large as those of the moon.By simple geometry, then, you can say that . . .-- the Earth's surface area is 13.462 times that of the moon,-- Earth's volume is 49.39 times the Moon's volume.(If you're in the league of those that are comfortable with mathematical equationsand like to toss them around, then you find that some consider the phrase "timessmaller" to be quite arbitrary, while to others, it has no meaning at all.)
