Answer:
1790.49 (um, maybe you make a typo or I did it wrong, but that’s what I got)
Step-by-step explanation:
150/pi is 47.7464829276, so that’s the diameter
47.7464829276/2 is 23.8732414638, and that’s the radius
23.8732414638 to the power of two is 569.931657988
If you multiply 569.931657988 by pi, you get 1790.49310978
