This is the concept of areas and circumference of the solid figures;
The circumference of the cylinder whose radius is 4 m will be given by;
C=2πr
C=2*π*4
C=8π m=25.133 m
What we know is that a 6 foot tall tent casts a 15 foot shadow. Lets represent that given this way: 6 = 15
So, the unknown (y), or what we want to know, is how tall the cardboard box if it has a 6 foot long shadow (noticeably the same height as the tent):
y = 6
6 = 15
y = 6
(6 x 6) / 15 = y
36 / 15 = y
2.4 = y
The height of the cardboard box is 2.4 feet.
Hello there!
According to the chart, you can see that for every lawn Nina mows, she earns $15. So it's increasing by 15 per yard.
Let's see if this will help:
1 yard= $15
6 yards = ???
I don't want to give you the answer right away, since I want you to learn how to do it. :)
I hope my hint helped!!
(If you're really stuck, take 6 times 15)!
Hope this helped!!
