10 pt Question 7 The circumference of a circular ice skating rink is 408.2 m. What is the approximate area of the skating rink? Use 3.14 for a 03 65 m2 O 130 m2 O 204.1 m 13, 266 m 2 Previous Next​

9514 1404 393

  (d)  13,266 m²

Step-by-step explanation:

The area in terms of the circumference is ...

  A = C²/(4π)

Filling in the given values, we have ...

  A = (408.2 m)²/(4×3.14) = 13,266.5 m²

The area of the skating rink is about 13,266 square meters.

answer:

125 yards

explanation:

75+50=125. that is my answer

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
