## Python Math: Exercise-8 with Solution

Write a Python program to calculate the area of a sector.
Note: A circular sector or circle sector, is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector.

Sample Solution:-

Python Code:

``````def sectorarea():
pi=22/7
angle = float(input('angle measure: '))
if angle >= 360:
print("Angle is not possible")
return
print("Sector Area: ", sur_area)

sectorarea()
```
```

Sample Output:

```Radius of Circle: 4
angle measure: 45
Sector Area:  6.285714285714286
```

Python: Get the Key Whose Value Is Maximal in a Dictionary

```>>> model_scores = {'model_a': 100, 'model_z': 198, 'model_t': 150}
>>> # workaround
>>> keys, values = list(model_scores.keys()), list(model_scores.values())
>>> keys[values.index(max(values))]
'model_z'
>>> # one-line
>>> max(model_scores, key=model_scores.get)
'model_z'
```
