C
Step-by-step explanation:
The answer is c. It adds to the weight of each box by 10 and multiplies by 12 to represent the 12 boxes.
Answer:
circle: 6490.9 cm², quadrant: 1622.7 cm²
Step-by-step explanation:
The circumference of the entire circle is known as 2πr and it is 4 times the given value, since a circle has 4 quadrants:
2πr = 4·71.4 = 285.6, so r = 285.6 / 2π ≈ 45.45
The area of a circle is πr², filling in the value for r we just found:
πr² = π 45.45² ≈ 6490.9 cm²
So the area of a quadrant is one fourth of that:
6490.9/4 = 1622.7 cm²
The question about "its area" can denote the entire circle, or just the quadrant, so two answers are provided.
3.
x = 3 because the 2 legs of 45-45-90 triangle are equal
y^2 = 3^2 + 3^2 = 18
y = sqrt 18 = 3 sqrt2
