3.14*4.1^2

- rvc

4.1 is the length or diameter or radius?

- Liv1234

Radius

- rvc

so \(\pi\) (4.1)^2

- Liv1234

52.7834

- rvc

what is the square of 4.1 ?

- rvc

here we need not multiply the value of pi since the answer is in pi

- Liv1234

So, 16.81?

- Liv1234

That's the square of 4.1

- rvc

correct :)
All The best

- Liv1234

Like, can you go over it with me?

- rvc

@aryandecoolest please help :)

- butterflydreamer

well they've given us a scale where
1cm = 10 ft.
So if we plant the trees
4.7 cm = ? ft
You basically want to change from 4.7cm INTO feet using the fact that 1cm = 10ft.
Sooo since,
1cm = 10 ft
4.7cm = 10 * 4.7 ft = ? ft

- Liv1234

47! But would it be ft or cm?

- butterflydreamer

correct :) Read what i wrote carefully...
we are converting cm ----> ft
Therefore 4.7 cm -----> 47 ft right? :)

- Liv1234

That makes sense(: Can you help me with a couple of other questions?

- rvc

good job @butterflydreamer thanks :)

@rvc can you help me with that question i just put up?(:

- rvc

yes
cross multiply

- Liv1234

I do know how to cross multiply, but this one confuses me.

- Liv1234

Also, I need help with one more question after this one.

- rvc

example
\[\frac{ x }{ 15 }=\frac{ 5 }{ 2 }-->x=\frac{ 5 }{ 2 } X 15\]

- Liv1234

So, 5/7*56?

- Liv1234

Which would be 40?(:

- Liv1234

So, would it be 40?

- Liv1234

@rvc Can you help me with another question please??(::

- rvc

okay

This is the last one I need help with(:

- rvc

the polygons are similar
so the sides will be in proportion

- Liv1234

So, how do we figure it out?

- Liv1234

Wait wait wait!! So, 18*1.5=27. And 6*1.5=9. So would the answer be 9?

- rvc

\[\rm \frac{ AD }{ JM }= constant~ ratio\]

- rvc

you are right

- rvc

All The Best :)

- Liv1234

Thank you(:

- rvc

- Liv1234
