Answer:
£191.36
Step-by-step explanation:
Sum the parts of the ratio, 1 + 4 = 5 parts
Divide 320 by 5 to find the value of one part of the ratio.
320 ÷ 5 = 64 ← value of 1 part of the ratio , thus
4 parts = 4 × 64 = 256
Thus he bought 64 first class and 256 second class.
Cost = (64 × £0.67) + (256 × £0.58)
= £42.88 + 148.48
= £191.36
X = multiplication
h = height
r^2 = radius squared
Formula of a cylinder: Pi x r^2 x height
So, if 176 = 3.14... times 4^2 times h
Then, 176 = 3.14 times 16h
Next, 176 = 50.24h
Finally, 3.5 = h
You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.
