Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm

The answers I gave are only if you want them in 10's
We know that
2 liters of pure water = 0 % of sugar
8 liters of syrup = 48% of sugar
Water = (2 liters x 0%) = 0 total sugar liters
Syrup = (8 liters x 48%) = 3.84 total sugar liters
Total liter mix =8+2-----> 10 liters
Total liters of sugar = 0 + 3.84 = 3.84
if 10 liters-----------> 100%
3.84 liters--------> x
X=3.84*100/10-----> x=38.4%
the answer is
38.4%
