A wheel on Ritas bicycle is 0.7 M in diameter read a race is the bicycle for 90 M how many times does the wheel turn is the bicycle travels a distance use the value 3.14 for pie round your answer to the nearest 10th do not round any intermediate steps

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .

42.4

step-by-step explanation:

convert to decimal

-2/

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
