Answer:
53.3
Step-by-step explanation:
Add one standard deviation to the mean:
45 +1(8.3) = 53.3
+1 standard deviation away from the mean is 45+1(8.3)
The new volume is 4 times the old volume ♡
I believe it's 6.5 hours
130/20=6.5
Not sure tho.
V = pi * R^2 * h
R = (V / (pi * h))^1/2 = (141.3 / (3.14 * 5))^1/2 = 3 cm
