The answer would be true.
The answer is D. The +1 refers to the extra cup leftover from a previous bag. X represents how many cups are in each bag, and that is what you need to know. The three represents how many bags she bought, and the 25 represents how many cups of birdseed she had overall.
Hopefully this helps!
B............................................. it’s b I took the test before
Answer:
- π is the area of a circle of radius 1
- π is the circumference of a circle of diameter 1
- π is the constant of proportionality relating the diameter of a circle to its circumference
Step-by-step explanation:
Area of a circle = πr² or πd²/4
Circumference of a circle = 2πr or πd
r is the radius
d is the diameter
If radius = 1
Area = π(1)²
Area = π
hence π is the area of a circle of radius 1 is CORRECT
Given d = 1
Area = πd²/4
Area = π(1)²/4
Area = π/4
Hence π is the area of a circle of diameter 1 is INCORRECT
For the circumference;
C = 2πr or πd
If r =1
C = 2π(1)
C = 2π
Hence π is the circumference of a circle of radius 1 is INCORRECT
Also if d = 1;
C = πd
C = π(1)
C = π
hence π is the circumference of a circle of diameter 1 is CORRECT
Since C = πd, then π is the constant of proportionality relating the diameter of a circle to its circumference is CORRECT
