Write and solve an equation of ratios:
9 ft 22 ft
------- = -----------
h 99 ft
This is appropriate because h is greater than 9 ft.
cross-multiplying, we get
9(99) ft^2 = 22*h*ft
Then h =40.5 ft (which is the height of the building)

Answer:
18. 84 ft² or 18.85 ft² when rounded to the nearest tenth
Step-by-step explanation:
2πrh+2πr²
2× 3.14 × 1 × 2= 12.56
2 × 3.14 × 1² = 6.28
12.56 + 6.28 = 18.84
Have a great day :)
Answer: 8 m/s
First let’s convert the time to seconds. There are 69 seconds in a minute so 1 minute and 40 seconds is 60 +40 second which totals to 100 seconds
Now to get the speed in meters per second we divide the total meters run by the total seconds
So the speed will be 800m/100s = 8m/s
