I think that the length of DE is 4. you can add 0.5 to each side of BC in order to find the length of EF since EF starts 0.5 before BC does and therefore also ends 0.5 after BC since the circle is symmetrical.
Answer:
4. 20.8 in
5. 60 degrees
6. i cant see number 6 so yah
Step-by-step explanation:
C=2π√150 ft
Or, C≈76.95 ft
Comment if you want to see how I did this.
The perimeter means the sum of all sides.
So, In pentagon, it would be: 5(15) [ With five sides ]
In short, Your Answer would be Option C
Hope this helps!
