How long does it take a plane traveling at a constant speed of 121 meters per second to fly once around a circle whose radius is 4230 m?
velocity: v = 121 m/s radius: r = 4230m circumference: C = 2 * (pi) * radius = ~26578m time: t = s/v = distance travelled / velocity = circumference / velocity = 220 s
What is the relationship between the perimeter of the hexagon and the circumference of the circle?
A hexagon is divided into 6 equilateral triangles; the circle around the hexagon has a radius the length of one of these triangles. So the circumference is S x 2pi, s being the side of the hexagon. The perimeter of the hexagon is 6s. So the relationship is that you multiply it by 1/3 pi
What s the area of a circle with 17.2 radius?
A circle with a radius of 17.2 units has an area of 929.41 square units.
What is a A line segment that connects the center and a point on s circle?
It is the radius of the circle
What is a radiu s of a circle?
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
All the parts of the circle?
Geometrically, the parts of a circle are the diameter, radius, chord(s), circumference, arc, sector, segment, tangent, secant, the minor sector, and the major sector.

What do feet in a circle mean?
Feet, singular foot, is a unit of measurement, equal to 0.3048 meters. "Feet in a circle" may mean that the circlés radius, its diameter, or its circumference has a certain number of feet.

What is area of s circle with 1 inch radius?
The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.
How do you find the area of a circle from a radius?
S = (pi) * (radius)2
What s the area of a circle with 17.2 radius?
A circle with a radius of 17.2 units has an area of 929.41 square units.
If the perimeter of a square is 36 what is the circumference of a circle?
If you mean a circle inscribed in the square: C = circumference, π = pi, r = radius, s = side, P = perimeter C = 2πr r = s/2 C = πs s = P/4 C = πP/4 So for this problem, the circumference is 9π, or about 28.3 If you mean a square inscribed in the circle, the computations are practically the same, except: r = sqrt(2)s/2 C = sqrt(2)πs C = sqrt(2)πP/4 So for this problem, the circumference is sqrt(2)9π, or about 40.0
What is a A line segment that connects the center and a point on s circle?
It is the radius of the circle
If the diameter is 8 what is the cirumference?
remember that the diameter is the distance across the plane of a circle that passes through the center point of a circle. The radius is half this distance. The circumference of a circle (the distance around the outside) is determined by the arc length 's'. 's' equals the square of the radius times the angle of the circle, in this case 360 degrees. We havr to convert 360 degrees to radians to do the math and that equals 2 times Pi. this sound complicated but it's not. The equation works out to be Circumference = 2 x (radius squared) x Pi or C = 2 x (16) x Pi C = 32 x Pi use your calculator for pi or multiply 32 by 3.14
What is a circle's area if it's circumference is 12π?
the area s 45pie!
What s the formula for the area of a circle?
The formula for the area of a circle is πr2, or pi x radius^2 The radius of a circle is the diameter divided by two, and pi is approx. 3.1415926535
