Answer:
Chang get $853.35 for selling the gold.
Step-by-step explanation:
To calculate how much money can Chang get for selling the gold we have to know the conversion between ounces and grams.
We know that 1 ounce is equivalent to 28.3495 grams.
Then, if Chang sold the 21 g that receive from his uncle, the amount of money he gets is:
Chang get $853.35 for selling the gold.
Answer:
310.6m^3
Step-by-step explanation:
Hi there,
Area of a circle with 4m = π(2)² = 4π m²
Area of a circle with 6m = π(3)² = 9π m²
Difference = 9π - 9π = 5π = 16 m² (nearest m²)
Answer: 16 m² (Answer B)
Hope it helps,

Answer:
Area = 228 m²
Perimeter = 60 m
Step-by-step explanation:
The figure given shows a rectangle that has a cut triangular portion.
✔️Area of the figure = area of rectangle - area of the triangular cut portion
= L*W + ½*bh
Where,
L = 20 m
W = 12 m
b = 20 - (8 + 8) = 4 m
h = 6 m
Plug in the values
Area = 20*12 - ½*4*6
Area = 240 - 12
Area = 228 m²
✔️Perimeter = perimeter of rectangle - base of the triangular cut portion
= 2(L + W) - b
L = 20 m
W = 12 m
b = b = 20 - (8 + 8) = 4 m
Plug in the values
Perimeter = 2(20 + 12) - 4
= 2(32) - 4
= 64 - 4
Perimeter = 60 m
