Answer:
Step-by-step explanation:
Total weight of aluminum cans that Pete collected for recycling is 47 pounds.
Total weight of aluminum cans that Jo collected for recycling is 52 pounds.
They can get $0.21 per pound for the cans. Therefore,
The total amount that Pete will get for collecting 47 pounds of aluminum would be
0.21 × 47 = $9.87
The total amount that Jo will get for collecting 52 pounds of aluminum would be
0.21 × 52 = $10.92
The total amount of money that they would get is
9.87 + 10.92 = $20.79
Answer: 9 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
Surface area if a cylinder (S)= 2 π r2 + 2 π r h
Where r is the radius and h is the height
Diameter is equal to 2r , so in our case:
14 =2r
r = 14/2 = 7 meters
Replacing with the values given and solving for h:
224 pi = 2 π 7^2 + 2 π 7 h
224 π - 2 π 7^2 / 2 π 7= h
703.71 -307.87 /43.98 = h
9 = h
