For all circles , however, large or small The diameter is twice the radius.
Diameter(d) equals(=) radius(r) plus(+) radius(r).
d = r + r
d = 2r .
NB The diameter is a straight line from the circumference to the centre , and then out to the opposite sided circumference.
It is NOT an angled line centred on the central point.
What else can I help you with?
What is the radius of a circle with the diameter of 6?
The diameter is the length of a straight line, from one side of the circle to the other, passing through the centre. The radius is a straight line from the circle centre to the circle itself and is always = half the length of the diameter, so 6 * 0.5 = 3
What is the length of a biggest chord of a circle of radius 4cm?
It is the diameter which is twice the radius giving a length of 8 cm
How is 25.133 the circumference of a circle with a radius of 4?
Radius = 4 so diameter is 8. 2xR = D Circumference formula: C = pi x diameter So 25.133 = 3.14 x 8
What is the circumference of 8cm?
Circumference of a circle: 2*p*radius or pi*diameter
What is the equation of a circle whose diameter's end points are at 2 -3 and 8 7?
The mid point of the diameter is the circle's centre: Mid point of (2, -3) and (8, 7) is ((2 + 8)/2, (-3 + 7)/2) = (5, 2) The radius is half the diameter, but as the equation for a circle requires the radius squared: radius = diameter/2 → radius² = diameter² / 4 Diameter (and diameter²) can be found using Pythagoras: diameter² = change_in_x² + change_in_y² = (8 - 2)² + (7 - -3)² = 6² + 10² = 136 → radius² = 136/4 = 34 Circle with centre (X, Y) and radius r has equation: (x - X)² + (y - Y)² = r² → (x - 5)² + (y - 2)² = 34 → x² -10x + 25 + y² - 4y + 4 = 34 → x² + y² - 10x - 4x - 5 = 0
What is the radius of a circle with a diameter of 8 centimeters?
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
What is the diameter of a circle with a radius of 8 centimeters?
The diameter is double the radius, and the radius is 1/2 of the diameter.If the radius is 8 cm, then the diameter is 16 cm.
What is a diameter of 8 centimeters?
A diameter of 8 centimeters means that a line drawn through the center of a circle from one edge to the other measures 8 centimeters. A circle with a diameter of 8 centimeters has a radius of 4 centimeters, an area of 16*pi centimeters, and a circumference of 8 * pi centimeters.
The diameter of the circle is 16 centimeters the radius?
The radius is 8 cm (r = d/2).
If the diameter of a circle is 16 centimeters than what is the radius?
Radius is half the diameter, so the radius mentioned in the question would be 8 cm
What is the diameter of a circle that has a radius of 4 centimeters?
It is: 2*4 = 8 cm
What is the volumn of a cylander with the base of 8 centimeters and the height is 10 centimeters?
It depends on what you mean by base. The radius or the diameter of the circle? If the diameter is 8 cm it's 502.4. If the radius is 8 cm it's 2009.6.
What is the area of a circle with a diameter of 8 centimeters?
The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.
What would be radius of a circle with a diameter of 8 inches?
Radius = 1/2 diameter. So, if the diameter is 8", then radius of the circle is 4".
What is the circumference of a circle with a radius of 8 centimeters?
If the radius of a circle is 8 cm, the circumference will be: 50.3 cm (C = r x 2 x Pi).
What is the circumference of a circle that has a diameter of 8 centimeters?
The circumference of a circle with a diameter of 8 centimeters is = 8*pi cm
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
