Answer:
Step-by-step explanation:
An easier way to do this type of problem, is to break it down,
10,000/1,000 is the BIG SCARY Problem, think of it like 10/1,\
1 goes into 10, 10 times,
So, what is 1,000x10?
10,000
Answer, 10
Pattern, is that is decreases by 1,000 every time and now you know
We know that
cos 45°=√2/2------> equation 1
in the triangle
cos 45°=m/(9√2)----> equation 2
equals 1 and 2
so
√2/2=m/(9√2)---> 9√2*(√2)=2*m-------> 9*2=2*m-------> m=9
the answer is
m=9 units
The Surface area of the whole cone is 4408.56 cm²
The Surface area of the tips that is removed is 376.8 cm²
The Surface area of the megaphone(hollow) is 2712.96 cm²
<h3 /><h3>What is surface area?</h3>
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape.
Therefore,
Surface area of the whole cone = πr² + πrl
Therefore,
Surface area of the whole cone = πr(r + l)
where
- r = radius = 18 cm
- l = edge length = 60 cm
Surface area of the whole cone = 3.14 × 18(18 + 60) = 4408.56 cm²
Surface area of the tips that is removed = 3.14 × 4 (18 + 12) = 376.8 cm²
Surface area of the megaphone(hollow) = πrl
Surface area of the megaphone(hollow) = 3.14 × 18 × (60 - 12) = 2712.96 cm²
