The formula for the radius of a sphere is:
r(s) = sqrt[s/(4pi)]
This is based on the formula that s = 4pi*r^2
As can be seen, as the surface area increases, s/4pi increases, and sqrt(s/4pi) will also increase, meaning that the radius will increase. This continues until the balloon reaches the maximum s = 1500 cm^2.
The correct answer is the first choice:
<span>As the surface area of the balloon increases, the radius of the balloon increases until the maximum surface area is reached.</span>
4 is the correct answer i believe! :) sorry if wrong.
please put brainliest!
Answer:
1989xsquared y + 585xsquared+ 2618xy + 770x - 8075y - 2375
Step-by-step explanation:
(9x + 25) x (13x - 19) x (17y + 5)
(117x squared - 171x + 325x - 475) x (17y + 5)
(117x squared + 154x - 475) x (17y + 5)
The fourth one best summarizes the passage
Answer:
2.5 is less than 1,950.
Step-by-step explanation:
The decimal place is at the end of 1,950.
The decimal place is in the middle of the 2 and the 5.
Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.
You can subtract both values.
1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.
0 < 1,947.50.
Therefore, 2.5 < 1,950
