Answer: 48cm^2
Step-by-step explanation:
The formula for area of rectangle is length × width
So u do 12 × 4 = 48cm^2
When you divide 20/6 you get 3.33 which is how many ounces John eats in a day. And then multiply what he gets everyday by 15 and you would get 49.95
ANSWER: 49.95

3/5 = 0.60
Then you find out which is the smallest: 0.59
Middle: 0.60 (3/5)

DONE! hope this helped!
Answer: Number of sand bags are 105
Step-by-step explanation:
Alright, lets get started.
The diameter of pool is given as : ![20 \ \text{feet}](https://tex.z-dn.net/?f=20%20%5C%20%5Ctext%7Bfeet%7D)
The radius of pool will be : ![r=\frac{20}{2}=10](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B20%7D%7B2%7D%3D10)
So the area of the pool will be:
Area = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Area = ![\pi *10^2](https://tex.z-dn.net/?f=%5Cpi%20%2A10%5E2)
Area = ![100 \pi](https://tex.z-dn.net/?f=100%20%5Cpi)
Area = ![314.16](https://tex.z-dn.net/?f=314.16)
3 square feet is covered by 1 sand bag, so
314.16 square feet will be covered by : ![\frac{314.16}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B314.16%7D%7B3%7D)
So, no of sand bag = ![104.7](https://tex.z-dn.net/?f=104.7)
Rounding off to nearest number
Number of sand bags are 105 : Answer
Hope it will help :)
