Well, they're saying 9 with an exponet of 2 multiplied by something equals 27..... Hmmm.....
Answer:
Volume of Cylinder A is pi times the area of the base times the height
π r2 h = (3.1416)(4)(4)(15) = 753.98 ft3
Volume of Cylinder B is likewise pi times the area of the base times the height
π r2 h = (3.1416)(6)(6)(7) = 791.68 ft3
After pumping all of Cyl A into Cyl B
there will remain empty space in B 791.68 – 753.98 = 37.7 ft3
The percentage this empty space is
of the entire volume is 37.7 / 791.68 = 0.0476 which is 4.8% when rounded to the nearest tenth

Answer:
9
Step-by-step explanation:
2 x 5 = 10
9 x 5 = 45
10:45 = 2:9
Answer:320
Step-by-step explanation:
2/5 of the students surveyed lisen to country. So to make the percentage fit the total student population, you figure out what your 2/5 is in a percetnage. That comes out to 40%. so, 40% of 800 is 320.
Pi is canceled out
so 3/4 x 180 = 135
hope it helps
