Answer: V≈56.55
Step-by-step explanation:
V=πr2h
3 = radius
2=height
Fill in the formula = V=πr2h=π·32·2≈56.54867
<u>V≈56.55</u>
Answer:
or 1.5
Step-by-step explanation:
Now we know it's a dilation. So we can use any two points. I chose V and V'.
V: (3,6)
V': (2,4)
So how we get from 6 to 4?
You can tell it's 1.5 aswell because 4 times 1 is 4 and 4 times 0.5 is 2. Add them to get 6.
Therefore, the dilation factor is 1.5.
Answer:
see explanation
Step-by-step explanation:
2 × 
= 2 × 10 × 10 × 10 × 10
= 2 × 100 × 100
= 200 × 100
= 20000
And
= 2 × 2 × 2 × 2
= 4 × 4
= 16
1) Now,
a + 27° = 90° (right angle triangle)
◆ a = 63°
2) Now,
b + b + b = 90° (right angle triangle)
or, 3b = 90°
◆ b = 30°
3) Now,
c + c + 40° = 90° (right angle triangle)
or, 2c = 90° - 40°
or, c = 50°/2
◆ c = 25°
4) Here,
◆ e = 41° (vertically opposite angle)
◆ f = 82° ( vertically opposite angle)
Now,
d + e + f = 180° (straight angle)
or, d + 41° + 82° = 180°
or, d = 180° - 123°
◆ d = 57°
Then,
◆ g = d = 57° (vertically opposite angle)
It is all correct answer...
I hope u understand...
Thank you ♥♥ my cutie...

Calculate volumes
v=lwh
vinitial=6*5*5=150
vnew=6*15*15=1350
new/initial=1350/150=9
