Well, when an ellipse has zero eccentricity and is called a circle, its major and minor
axes are both the same length. In fact, every axis through the center has the same
length, even the oblique ones, and every one of them is called a "diameter".
So the semi-major axis of a circle is half of the diameter, typically referred to as the "radius".
In your circle, that's 12 cm.
What else can I help you with?
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What is the circumference of 52 m semicircle?
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
What is the red line segment called in a ellipse?
Whichever segment it is to which you are referring, it does not need to be red; it can be any color.The segment that intersects both foci is called the semi-major axis. The segment that is perpendicular to the semi-major axis with one end midway between the foci is called the semi-minor axis.
How do you find the perimeter of a rectangle with a semi circle attached to it?
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
How do you find the center and semi-major and semi-minor axis for ellipse with equation 16x2 plus y2 equals 16?
An ellipse with centre (xo, yo) with major and minor axes a and b (the larger of a, b being the major axis) has an equation of the form: (x - xo)2 / a2 + (y - yo)2 / b2 = 1 The semi-major and semi-minor axes are half the major and minor axes. So re-arrange the equation into this form: 16x2 + y2 = 16 x2 + y2 / 16 = 1 (x - 0)2 / 12 + (y - 0)2 / 42 = 1 Giving: Centre = (0, 0) Major axis = 2 Semi-major axis = 2/2 = 1 Minor axis = 1 Semi-minor axis = 1/2
How can one determine the semi-major axis of an orbit?
To determine the semi-major axis of an orbit, you can measure the distance between the center of the orbit and one of its furthest points. This distance is half of the longest diameter of the elliptical orbit and is known as the semi-major axis.
What is the area of a semi-circle with a diameter of 5?
The area of a semi-circle with a diameter of five is: 9.817 units2
How do you find the diameter of a semi-circle?
It is the length of the base of the semi-circle.
How do you find the perimeter of a semi circle with a diameter of 12mm?
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
What is the Perimeter of semicircle and quadrant circles?
The semi-circle is 0.5 X pi X diameter + diameter The semi-circle is 0.5 X pi X diameter + diameter
What is the ratio of the diameter of moon to the diameter of the earth?
The Moons semi-major axis is 384,399 km The Moons mean diameter is 3474.2 km. So about 110 moons would fill this gap.
What is the semi major axis of ganymede's orbit around Jupiter?
Ganymede's semi-major axis is approximately 1,070,400 kilometers.
Arc whose endpoints are on a diameter?
Semi-circle.
What is the straight edge on a semi circle called?
The diameter.
Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What shape is created when a circle is folded along the diameter?
When a circle is folded along its diameter, it creates two congruent halves or semicircles.
What is formula of perimeter of semi circle?
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)
