Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
Answer:
LCM: 1,800
GCF: 150
Step-by-step explanation:
150:600 = 150 / 600 = 0.25 (that's pretty much what a ratio is, just a fraction or part of a whole.)
150 is the greatest common number that will factor into all three, and the least/smallest number they all multiply into is 1,800
Answer:
2304 cubic inches
Step-by-step explanation:
Volume of the green is (12)(12)(6)=864
Volume of the blue = (18)(8)(10)=1440
So the total volume is 864 + 1440 = 2304 cubic inches

Answer:
The area of the two-dimensional cross section is 
Step-by-step explanation:
we know that
The two-dimensional cross section that is parallel to face ABC is a triangle congruent with the triangle ABC
Therefore
Calculate the area of triangle ABC
we have that
Triangles ABC and DEF are congruent
so
substitute
