Answer:
A = 81.681409 (81.64 for 3.14 as pi) B = 4.65222141 (4.65458109 as 3.14 for pi) rotations
Step-by-step explanation:
To figure out how far one full rotation is (which is the circumference) you do the circumference formula: C = 2 pi r
C = 2 pi 13
C = 26pi
C = 81.681409
To figure out how many rotations C can fit into 380, divide 380 by C
380 / 81.681409 = 4.65222141
Answer:
n=

Step-by-step explanation:
Let's solve for n.
(((−
