6a) Find the ratio using the information given on the radii of the cylinders;
6.3/5.4 = 7/6 ratio
6b) It is stated that the cylinders are similar, using this information write out the information as;
Let x be the length of the bigger cylinder.
6.3/5.4=x/10.2 --> we can only write this when we know the shapes are similar
(6.3×10.2)/5.4=x
11.9 cm=x
As you can see, the rest of the question evolve around these to basic key concepts. Try to understand why they work out and how they were found. If you have any questions about how I found the answers, you can ask me.
Hope I helped :)
Sorry boo I can’t see it well it’s too small
Answer:
x=10
Step-by-step explanation:
I guess solve for x
5x=50
x=10
Answer:
42
Step-by-step explanation:
Angle ABD = Angle CBD + Angle ABC
You know ABD is 70, CBD and ABC are in terms of x
70 = 5x + 13 + 3x + 33
70 - 13 - 33 = 8x
24 = 8x
3 = x
Replacing x in Angle ABC:
3 * 3 + 33 = 42
