p.s a calculator does exist.
First we need to determine the circumference of the bath.
Circumference = Diameter X pi
6(pi) = 18.84 feet
and the girls want to put perches that are at least 3 feet between each other so you can just divide the circumference by 3
18.84 / 3 = 6.28 so 6
If you don't understand the concept then think of it like this, if you have in total 18.84 feet and you want to place something down every 3 feet then start subtracting 3 from your total till you can't add anymore perches.
18 - 3 = 15
15 - 3 = 12
12 - 3 = 9
9 - 3 = 6
6 - 3 = 3
3 - 3 = 0
We subtracted 3, SIX times so we added 6 perches
Answer:
12 feet
Step-by-step explanation:
Sometimes, a simple drawing is a great way to start! In the attached drawing, the red line represents the ladder, the brown represents the ground, and the black represents the building!
We want to find the side of the triangle from where the ladder meets the building to where the building meets the ground. This can be found using trigonometric identities, namely sine:
Plug in known values:
Rearrange to isolate the variable:
Simplify!
Round to the nearest foot:
