<h3>Given:</h3>
<h3>To find:</h3>
<h3>Solution:</h3>
We can divide the given shape into a triangle and a rectangle.
We'll have to use Pythagoras Theorem.

In this question we have to find the hypotenuse so we'll have to add.
Let's substitute the values according to the formula.




Now, we can find the value of "x"
- Adjacent= 7 cm
- Opposite= 6 cm
- Hypotenuse= 9.22 cm
We can use any one from SOHCAHTOA.
Here I'm using tan.

Let's substitute the values according to the formula.

We'll have to use tan inverse.


Answer: the 4th one I think
Step-by-step explanation:
V = 60 as the triangle is looking like a equilateral triangle
Area of a circle is PI x r^2
The area is 169PI which means r^2 = 169
Find r by taking the square root of 169:
r - sqrt(169)
r = 13
The radius is 13 m
