______
Answer:
2/3 < 3/4
___________________
Step-by-step explanation:
2/3 = (2*4)/(3*4)=8/12
3/4 = (3*3)/(4*3)=9/12
Since 9/12>8/12 then 3/4>2/3

Answer:
227.75 cm
Step-by-step explanation:
a coin (Circle) with diameter 2.9cm
(radius) r = diameter ÷ 2
r = 2.9cm ÷ 2
r = 1.45cm
1 complete revolutions (perimeter or circumference of a circle ) = 2πr
= 2 × π × r
where r = radius, π is a constant = 22/7
= 2 × 22/7 × 1.45
= 9.11cm
thus in one complete revolution the coin travels a distance of 9.11cm.
therefore in 25 complete revolutions the coin will travel a distance of = 25 × 9.11 cm = 227.75 cm.
The distance covered in complete 25 revolutions of a coin with diameter of 2.9 when it's rolled is = 227.75 cm
