Answer is 15
A=1/2 bh
A=1/2 5(6)

Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
3/4
1/6 of the pot is 2/12
1/12 + 2/12 is 3/12
1 - 3/12 is 9/12 = 3/4
3/4 of the pot is left over
