Answer: r≈1.96
Step-by-step explanation:
C=2πr
Solving for r
r=C
2π=12.3
2·π≈1.95761
Answer: NO. if a/b > c/d, a/d is not greater than b/c
Step-by-step explanation: The the larger the number in the denominator, the smaller its value as it is represents fractional value, not a whole number. So when a "small" numerator is moved to a denominator, it increases in size, and the large number in the numerator moved to a denominator decreases in size.
Moving the denominator from a smaller fraction to the left side will diminish the value of the new fraction.
3/4 > 1/2 but 3/2 < 4/1
7/8 > 5/6 but 7/6 < 8/5
1/2 > 1/4 but 1/4 < 2/1
Answer:
The second one is no
i done know the first one though give me a second to solve
Step-by-step explanation:
Cos 60 = 1/2 --> Sin60 = sr(3)/2 = 0.866
Tan60 = 1/sr(3) = 0.577
