Simple


Let's see using the sin rule

R divided by the angle opposite to the prime number chord

This relation holds for all the prime numbers chords...

The sum of the opposite angles equals 360

While the sum of interior angles equals n-2 by 180

Solve for the rest..

the diameter should be 17
so r should be 8.5

Radius =8.
The radius when drawn beyond the center forms a perfect iscoceles triangle.
Also the radius line lies parallel to the other numbers.
If you draw the radius beyond the center it will give you 11 because an iscoceles triangle has the two top sides equal.
And if you add the other lengths
1+2+3+5=11.
So following the radius from outside to the center stops at exactly 3+5=8.

If you still don't understand it, forget it because I'm not a good teacher.

Applying circle theorem
Equal chords of a circle are equidistant from the centre of the circle
so technically r should be 11.

Next prime number = 17
Use perpendicular line to divide line 17.
Then use your SOH CAH TOA at angle 90 to get 8.5.
Answer = 8.5

You are more lazy, if you could post that without taking the time to post the solution.

Viewing the topic and studying the shape are enough to show seriousness especially when you are not with pen and paper at that moment.

8.5 QED
Re: If You Know Prime Numbers You Should Be Able To Solve This Shape (Photo) by dacool1(m): 9:32pm On Apr 15, 2019
Answer is 7
Since the chords are enclosed to form a cyclic polygon and are of lengths 1,2,3,5,7,11,13
Angle at center =360
Ratio of angles =1:2:3:5:7:11:13
Sum of ratio =42
Working with chord 7
Angle subtended by chord 7 =7/42 *360
ANGLE = 60
Length of chord =2rsin®/2
7=2rsin30
R=7/2sin30
R=7

The shape is a cyclic quadrilateral.prime nos are 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 etc.You can solve it by refering to circle theories.opp angles are supplementary etc. But what exactly do u want?sex?

R=17
Proof: 8,9,10,12,,15,16, can be divided with a number. BT 17 can only divide itself.

Adanairaland:
R = 17
17 in between 7 and 11,i disagree with u, what (r) need to reshape the folder is an odd number and 9 falls in that position so the correct answer is 9.
