Answer:
31.42
Step-by-step explanation:
you will need a calculator for this
you will need to do 2 x pi x r = C
2 x 3.14 x 5
2x5=10
3.14 x 10 = 31.42
you get 2 when you round to the nearest ten-thousandths
pi = 3.14159
The absolute value of b is equal to 7. Absolute value means the distance from zero. In simple terms, the positive version of the number. B could be 7 or -7, since both will be equal to 7 when you take their absolute value.
Using trigonometry
tan(x)=9/6
use your calculator to find x using tan-1(9/6) and you get 56.3° which is basically the first answer
Answer: B
Step-by-step: because in all of them the first ration can either multiply or be simplified to the next number but in B 4/7 can multiply or be simplified to it.
