\/
75/90 × 100%
(dividing 75 bad 90 by 5 )
15/18 × 100%
(dividing 15 and 18 by 3 )
5/6 × 100%
( dividing 6 and 100 by 2 )
5/3 × 50%
250/3%
83 1/3%
your answer ====> 250/3% or 83 1/3%
Okay, so this is exponential. The formula for the exponental function is Y=ab^x
a is the y-intercept
b is the rate/ratio
x is the time
According to the graph, (remember the y-intercept is in the y-axis) so 2 is the y-intercept.
Knowing what the y-intercept is, you know what the answer is.
A.
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.
