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>
A equivelint ratio is when u can multi or divide by both sides
Answer:
Circle f is a translation of circle d
For number 22:
7y=8x-14 ; y=6
Plugging in y, we get:
7*6 = 8x - 14
42 = 8x-14
56 = 8x
x = 7
Comparing answers, x is, indeed 7.
Hi there!
To start, let's find the area of the bases. Since we're finding the area of two triangles, we don't need to put a 1/2 in front of our equation. This leaves us with 24 x 5 for the area of our bases. Now, we need to find the lateral area. We have two congruent rectangles and one that is different. Using the provided measurements, this leaves us with 2(5 x 13) + 1(20 x 24). Next, we need to add the lateral area to the base area. This leaves us with the surface area, which is 730ft^2. Also, the perimeter of the base is 50ft, the height is 20ft, and the base area is 120ft.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
