Semicircle
A rainbow is a circle. What we see from almost any point on earth is a semicircle, or just a part of the rainbow. We can only see it from horizon to horizon, or just an arc of the whole rainbow. Occasionally we can see a full circle of a rainbow in the sky surrounding the sun, and sometimes multiple ones.
A semicircle means a half circle.
A rainbow forms a circular arc due to the refraction, reflection, and dispersion of sunlight in water droplets in the atmosphere. It appears as a semicircle or full circle when observed from above, such as from an airplane or an elevated location.
A rainbow results from sunlight passing thru raindrops that results in a prism effect that makes a complete circle. You only see a semicircle because of the horizon, but from an air plane you would see the full circle
Semicircle is HALF of a circle!
Half of A circle
A circle
semicircle
The circumference of a circle = 2π r = π a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the perimeter of the circle + the base length The perimeter of the semicircle = πa/2 + a = a(1 + π /2) feet
A rainbow forms a semicircle because it is created by the refraction, reflection, and dispersion of sunlight through raindrops in the atmosphere. The circular shape occurs because the angle of reflection and refraction is consistent for all raindrops within a specific range, resulting in a semicircular arc of color.
It is a half a circle STUPID!!!!!
