It is (5*pi/6)*8 = 20*pi/3 m.
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
Diameter divided by 2 equals radius r=d/2 For example, if the radius was 3.5, the diameter would be 7.
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
The answer depends on what information you do have: radius, arc length, central angle etc.
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
The measure of the central angle divided by 360 degrees equals the arc length divided by circumference. So 36 degrees divided by 360 degrees equals 2pi cm/ 2pi*radius. 1/10=1/radius. Radius=10 cm.
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
Diameter divided by 2 equals radius r=d/2 For example, if the radius was 3.5, the diameter would be 7.
If the radius of a circle is tripled, how is the length of the arc intercepted by a fixed central angle changed?
(arc length / (radius * 2 * pi)) * 360 = angle
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
The answer depends on what information you do have: radius, arc length, central angle etc.
The arc length divided by the radius is the angle in radians. To convert radians to degrees, multiply by (180/pi).

The length of an arc of a circle refers to the product of the central angle and the radius of the circle.
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
The measure of the central angle divided by 360 degrees equals the arc length divided by the circumference. So 18 degrees/360 degrees=arc length/(9 feet*2pi). 1/20=arc length/18pi feet; arc length=9pi/10 feet. It's refreshing to answer a question that is written with grammatical accuracy!
