In the diagram below, Circle O is inscribed in square ABCD . The square has an area of 625. What is the area of the circle?
1 answer:
Answer:
area of the circle = 490.625 unit²
Step-by-step explanation:
The circle is inscribed into the square ABCD . The picture illustrate a circle inscribed in a square. All the sides of a square is equal. The angles are also equal.
area of a square = L²
area of the square = 625
625 = L²
square root both sides
L = √625
L = 25
The length of each sides of the square = 25
Area of the circle = πr²
where
r = 25/2 = 12.5
area = π × 12.5²
area = 156.25π
area = 156.25 × 3.14
area of the circle = 490.625 unit²

Answer:
a = 2/5 = 0.4
b = 9/25 = 0.36
c = 19/50 = 0.38
Step-by-step explanation:
relative frequency = (number of desired results)/(total number of possible results)
a = 4/10 = 2/5 = 0.4
b = 18/50 = 9/25 = 0.36
c = 76/200 = 19/50 = 0.38
Minus 32a from both sides
17d=176-32a
divide both sides by 17
d=
I would help but only if you give me 20 points cause it’s hard
5x+13=4x+2+2x-9 6x-7=5x+13 x=20 80+24x+2=82 5x+13=113
Answer:
25+24= 49coins 49÷2.5 is 19.5 so there are 19.5 dimes in the bag I believe
