Question 8:
Your choice is correct: two figures are similar if all correspondant sides are in the same ratio.
In your case, the figure on the right have correspondant sides which are all three times the figure on the left, since
So, the two figures are similar and their ratio is 1:3.
Question 9:
We follow exactly the same approach: let's see if the radii and the heights are in the same ratio: the radii are in ratio
While the heights are in ratio
So, the answer is again yes, they are similar, and the ratio is 1.6.
Answer:
I think you're suppose to add the angles
Step-by-step explanation:
correct me if I'm wrong because as you can see ab CD are connected together even if you're still stuck I think the best thing is to ask your teacher.
Answer:
= 6
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 6 and r = 30 ÷ 6 = 5, thus
= 6
Step-by-step explanation:
to find slant height.
- l²=(a/2)²+h²
- l²=2.25+36
- l=√38.25
- l=6.18
total surface of square base pyramid =a²+2al
