Aspinner has 10 equally sized sections, 7 of which are gray and 3 of which are blue. the spinner is spun twice. what is the probability that the first spin lands on blue and the second spin lands on gray ?

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

we can also rewrite it as:
