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

4 ones place
2 tens place
6 hundreds place
5 thousandths place
8 ten thousandths place
2 hundred thousandths place
When the number after the number you want to round (we want to round the 8, the number after 8 is 5) is 5, 6, 7, 8, or 9 we round up, otherwise, we stay the same
5 is in the list so we round 8 up to 9.

Answer:
4,800
Step-by-step explanation:
(14,700- 1,500) / 2 h 45 m
= 13,200 / 2.75
= 4,800 L/h
