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:
G. Carla, Brenda, Marci, Susan
Step-by-step explanation:
The time given for all participants are in decimals except for that of Marci and Carla which are given in the form of mixed fractions.
Convert the mixed fractions into decimals, then compare the figures together to do the ranking.
Marci =
Carla =
The first four finishers from the 1st to the 4th are:
1. Carla - 46.9
2. Brenda - 46.97
3. Marci - 46.98
4. Susan - 47.21
Well dont you have to bring down the zeros than you will have the answer
