The arc length of AOCD would be 1/2 the circumference of a full circle.
Circumference = PI x diameter
The arc length of AOCD would become 1/2 x PI x diameter = 1/2 x PI x 4 = 4PI/2
Now you want the arc length of AD, which is intersected with the quadrant, replace the denominator with the radius of the quadrant.
The arc length is now 4PI/3
The answer is B.
The different combinations are:
1 n and 20 c
2 n and 15 c
3n and 10 c
4n and 5 c
5n

Answer:
I think it's 98 square metres.
Step-by-step explanation:
perimeter of base x height = 180
180/2 = 90
90 + area of base = 98
Literally just add it all up.
312.8+177.2+209=699 miles
