Answer:
7.7 square metres or 7.669 square metres of metal sheet
Step-by-step explanation:
Volume of cylinder = 2×22/7×r×100cm
15.4 litres = 15,400 cm cube
Radius = 15 400×7/22 × 50
= 98cm
Surface area of cylinder = (2×22/7×49^2) + (2×22/7×49 × 100)
= 15 092 + 61 600
= 76 692 square cm
= 7.669 square metres of metal sheet required

Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140
Since, we don't have the actual graph, I cannot give you a final answer. However, I can explain how to find the answer.
