Step-by-step explanation:
Answer:
a)=251.2 cm b)=50240 cm
Step-by-step explanation:
a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.
Therefore, C = 2 * 40 * 3.14 = 251.2 cm
b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.

Answer:
x = 12
Step-by-step explanation:
The similarity statement tells you corresponding sides have the same ratio.
AB/BC = FE/EC
x/10 = 6/5
x = 10(6/5)
x = 12
