Find the volume of the cylinder using the formula v = pixr^2 x height
V= 3.14 x 6^2 x 14 = 1,582.56 cubic cm
Area of of the rectangle = 16 x 11 = 176 square cm
The height will be the volume divided by the area
Height =1582.56/176 = 8.99 cm
The height is 8.99 cm ( round off as needed)

Answer:
Q2. Original 100%
New Selling price=100% - 25% = 75% of original
Sale price of bracelet= 75/100 × 44 = $33
Q3. 100%- 25%= 75%
Cost of table= 75/100 × 425= $318.75
Alternatively,
Discount= 25/100 × 425 = $106.25
Cost of table= $425- $106.25= $318.75
Q4. 10 cans ---- $4
1 can= 4÷10 = $0.40
15 cans= $0.40 ×15 = $6
Q5. Total number of children= 35+5= 40
Total people= 10+40 = 50
Thus, the ratio is 40:50= 4:5 (<em>divide by 10</em>)
