sorry, i only speak English. But I hope someone will help u :)
We start with converting gallons to liters. There are 3.785 liters in a gallon, so Sally consumed 9.4625 liters in that day. Multiplying that by 1,000 milliliters in a liter gives us 9,462.5 milliliters. Sally consumed 9462.5 milliliters in that day. Hope this helps!<span />
Answer:
7.8
Step-by-step explanation:
We are looking for the inner perimeter of the track. Since there are two semicircles, these mix to form one full circle so we can use the formula to find the circumference of the circle with a diameter of 60 m, which was given to us. With a diameter of 60m, the radius will be 30m. Now we can solve this problem.
C = 2πr
C = 2π(30)
C = 60π
The semicircle ends of the track are a distance of 60π m, and now we just need to add the lengths of the inner track which are 100 m each. So:
P = 60π + 100m + 100m
P = 200 + 60π
P = 388.5 m
Answer:
138.248cm²
Step-by-step explanation:
Surface area=2πrh + 2πr²
Surface area=2x3.142x2x9+ 2x3.142x2²
Surface area=113.112+25.136
Surface area=138.248cm²
