Acircle with radius x is shown below. the diagram is not drawn to scale. what is the value of x

You have one chord of length 28 and you know the distance of this chord from the center which is 8.if you rotate the radius so that it connects the center with one of the extremities of the chord you get a triangle rectangle, with legs 8 and 14 (half the chord).therefore, you can simply apply the pythagorean theorem: x =  √(8² + 14²)  =  √(64 + 196)  =  √260  = 16.1245hence, the radius is 16.1 units long.

Could you make it more clear?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
