There are 4 blue marbles
There are 2 black marbles
There are 3 red marbles
There are a total of 9 marbles
You minus the black marbles from the total
9-2=7
If there are 7 non black marbles then the ratio is 7:9
7:9 is the probability that you won't get a black marble

A sphere is inscribed in a cylinder. Use complete sentences and geometric formulas to compare the surface area of the sphere and
grandymaker [24]

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.
