# How does a planetary orbit subtend an arc?

Let's ramble around a bit and see if we can get to a place where the answer appears. Ready? Let's jump.. Planets rotate about the sun in their orbits. Some of the orbits are (MORE)

# What is the maximum angle subtended on the celestial sphere by the separation of Venus and the sun?

Because Venus orbits closer to the Sun than the Earth, the angle between Venus and the Sun can never reach 180 degrees (the Sun and Venus cannot be directly opposite each othe (MORE)

# What is the angle subtended by an arc of a circle equal in length to the radius of that circle?

The answer does not match. It is called a Radian that is used in Trigonometry , a special branch of mathematics which deals with study of triangles. "Tri" means three a (MORE)

# Angle subtended by an arc is double the angle subtended by it at any other point on the remaining part of the circle?

You can prove this just from knowing that the three angles of a triangle add to 180 degrees. Label the ends of the arc A and B, the circle's centre O and the "any other poi (MORE)

# The area of a circle is 72cm2 find the area of a sector of this circle that subtends a central angle of 3.14 over 6 rad?

A sector with a central angle of pi/6 is 1/12 from the area of the whole circle so: 72/12=6cm 2

# Prove that if chords of congruent circles subtend equal angles at their centers then the chords are equal?

let the two circles with centre O and P are congruent circles, therefore their radius will be equal. given: AB and CD are the chords of the circles with centres O and P respec (MORE)

# How to find length of arc if radius and angle subtended at the center are given?

Full circumference of the circle = (2 pi) times (radius) Arc is a fraction of the full circumference. The fraction is (angle subtended at the center) divided by (360 degre (MORE)

# What is a 90 degree angle subtended by?

May things, but the probable answer sought here is a diameter of a circle, at the circumference of the circle.

# What is the degree measure of an angle subtended by an arc whose length is 10 cm?

There is not enough information to answer the question. You need the radius (or diameter) of the circle.

# How long a piece of wire would you need to form a circular arc subtending an angle of 1.3 if the radius of the arc is 8.6 cm?

That depends on whether the angle is 1.3 degrees, radians, or some other unit. The first step is to calculate the circumference of a circle with radius 8.6 cm. This is 2 pi ti (MORE)
