The third and fourth options.
Janeka forgot to divide by 2 to get the radius and then square and multiply by pi.
Answer:
Option C is correct.
Step-by-step explanation:
Here, boy knows his height and shadow length
And he know the length of tree shadow.
We need to find height of the tree.
And tree and it's shadow makes right angle at the point of intersection.
So, S A S rule works here.
Answer:
2.5 would be 5 while 11.2 would be 22.4
Answer:
Yes
Step-by-step explanation:
The diagonal is given by
![\sqrt {{20^{2}+12^{2}}=23.3238075793812\approx 23.3](https://tex.z-dn.net/?f=%5Csqrt%20%7B%7B20%5E%7B2%7D%2B12%5E%7B2%7D%7D%3D23.3238075793812%5Capprox%2023.3)
Considering the attached diagram, since the radius is 25 miles but from radio tower the cabin is 20 miles East wards, it means it is within the radius considering rhe diagonal distance of 23.3 miles. Also, considering the North direction, the cabin being 12 miles away considering diagonal of 23.3 miles but the radius is 25 m it means the radius exceeds the position by 25-23.3=1.7miles.
Therefore, for both directions, the cabin is within the radius of the tower
