Answer:
about 3.78 3.78698225 given those numbers
Step-by-step explanation:
Answer:
The slant height of the cone affected is two times the slant height of original cone
Step-by-step explanation:
we know that
If the height and base radius of a cone are increased by a factor of to create a similar cone
then
the scale factor is equal to
therefore
the slant height of the cone affected is equal to the slant height of the original cone multiplied by the scale factor
Find the slant height of the original cone
Let
l-----> slant height of original cone
la-----> slant height of the cone affected
Applying the Pythagoras theorem
so
The slant height of the cone affected is two times the slant height of original cone

The perimeter of a shape is the sum of its side lengths.
<em>Joshua miscalculated the third length of the triangle</em>
First, we calculate the third length (x) of the triangle.
Because the triangle is right-angled, we can make use of Pythagoras.
So we have:
![x^2 = 7^2 + 7^2](https://tex.z-dn.net/?f=x%5E2%20%3D%207%5E2%20%2B%207%5E2)
![x^2 = 2(7^2)](https://tex.z-dn.net/?f=x%5E2%20%3D%202%287%5E2%29)
Take square roots of both sides
![x = \sqrt{2(7^2)](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B2%287%5E2%29)
![x = 7\sqrt{2](https://tex.z-dn.net/?f=x%20%3D%207%5Csqrt%7B2)
The other shape in the figure is a square.
So, the perimeter (P) is
---- i.e. the sum of the visible lengths
So, we have:
![P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7](https://tex.z-dn.net/?f=P%20%3D%207%20%2B%207%5Csqrt2%20%2B%207%5Csqrt2%20%2B%207%5Csqrt2%2B%207)
Evaluate like terms:
![P = 14 + 21\sqrt2](https://tex.z-dn.net/?f=P%20%3D%2014%20%2B%2021%5Csqrt2)
Hence, Joshua's error is that:
<em>He miscalculated the third length of the triangle</em>
