Answer:
1 : 1
Step-by-step explanation:
When a circle is inscribed in a cylinder, the height of the cylinder is equal to the diameter of the sphere and the radius of the cylinder is same as that of the sphere.
Let the radius of sphere is r.
height of cylinder, h = 2r
radius of cylinder = r
Surface area of sphere, A = 4πr²
lateral surface area of cylinder, A' = 2 πrh
A' = 2πr x 2r = 4πr²
The ratio of surface area of sphere to the lateral surface area of cylinder is 1 : 1.
The answer would be .81 becuase you can't round the 1 up to 2 becuase the number in the thousandths place is not above 5.

Answer:
so the lowest term is 1/10
hope this helps u
Let A be number of adult tickets brought
Let S be number of senior citizen tickets brought
8492 = 22A + 12S (1)
A = 556 - S (2)
Plug (2) into (1)
8492 = 22(556 - S) + 12S
8492 = 12232 - 22S + 12S
8492 - 12232 = -22S + 12S
-3740 = -10S
-3740/10 = -10S/-10
374 = S
S = 374
Note that there are several more steps you can take to check the answer and/or find A.
