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.
Answer: i can not answer bc there is no way to lol
Step-by-step explanation:
%/100=is/off
so you plug in the numbers and cross-multiply.
103times127 equal 13081.
than divide it by 100 the answer is 130.81
Answer:
Step-by-step explanation:
g(x) is shifted 5 down in the y axis, meaning you have to subtract 5 from the function, and is shifted 4 to the left in the x axis- meaning you have to add to the x's in the function.
Answer:
-9/4
Step-by-step explanation:
A perpendicular slope is on that is the negative reciprocal. current slope=4/9 and the negative recipocal is -9/4.
