What is the length of XPY in terms of pi?

2 answers:

6 0

Circumference = 2 x PI x r

= 2 x 3.14 x 30 = 60 PI
the area from x to y = 90 degrees
so XPY would be 360 - 90 = 270 degrees or 3/4 of a full circle

so XPY = 60 x 3/4 = 45 PI meters

Circumference of a circle = 2πr

Circumference of the whole circle= 2π(30) = 60π

360 - 90 = 270

Length XPY = 270/360 x 60π = 45π

Answer: 45π m

Explanation:

You can check your answer by making sure that each of the primes you found is actually a prime. (Compare to a list of known primes, for example.) After you have determined your factors are primes, multiply them together to see if the result is 73. If so, you have found the correct prime factorization.

<em>Additional comment</em>

73 is prime, so its prime factor is 73.

73 = 73
