From x=a to x=b, with n subintervls, the width between each is (b-a)/n
so from x=3 to x=5 and 4 intervales is (5-3)/4=2/4=1/2
increments of 1/2 each time
we need 4 of them
I see that xi is the right endpoint so I would guess that we take the right <span>Riemann sum
so we start at 3+0.5 or 3.5
so 3.5, 4,4.5,5
C I would say

i am not too sure if i am correct in this but i will give it a go. i apologise if i am incorrect. In finding the diameter the equation C/π. in finding the radius the equation is (C/π)/2
Part 1
Q2) c=650πcm
650 X π= c so d must be 650cm
Q4) c=241πcm
241 X π= c so d must be 241
Q6) c=802cm
c/π=d =802/π= 255.28cm (2DP)
Q8) c=962cm
c/π=d = 962/π= 306.21cm (2DP)
Answer:
Congruent
Step-by-step explanation:
The alternate interior angle theorem states that if two lines are parallel and are interesected by a line, the alternate angles on either side of the interior of the line are congruent. Angles two and three, in the interior, which are not shown, are also congruent and are both supplementary to 1 and 4.
