Answer:
18 m
Step-by-step explanation:
The given situation is equivalent to a right angled triangle as shown in the diagram attached.
AB is the height at which tree was cut.
And the top touches the ground at a point C.
So,
AB = 5 m and
AC = 12 m
Here, we have to find original height of the tree.
Original height of Tree = AB + BC OR AB + BC' (Because B is the point in height AC' of tree)
Let us consider the
.
As per pythagorean theorem:
![\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow BC^{2} = AB^{2} + AC^{2}\\\Rightarrow BC ^2=5^2+12^2\\\Rightarrow BC = \sqrt{169}\\\Rightarrow BC = 13\ m](https://tex.z-dn.net/?f=%5Ctext%7BHypotenuse%7D%5E%7B2%7D%20%3D%20%5Ctext%7BBase%7D%5E%7B2%7D%20%2B%20%5Ctext%7BPerpendicular%7D%5E%7B2%7D%5C%5C%5CRightarrow%20BC%5E%7B2%7D%20%3D%20AB%5E%7B2%7D%20%2B%20AC%5E%7B2%7D%5C%5C%5CRightarrow%20BC%20%5E2%3D5%5E2%2B12%5E2%5C%5C%5CRightarrow%20BC%20%3D%20%5Csqrt%7B169%7D%5C%5C%5CRightarrow%20BC%20%3D%2013%5C%20m)
Therefore the answer is :
Height of tree = 5+13 = <em>18 m</em>
Answer:
9.42m
Step-by-step explanation:
You have to find the circumference using C=2πR. We know that the radius =4 meters so then we can insert it into the formula to get the circumference which equals 8π. Then we divide 24m² by 8πm and get 9.42m.
