Elibri has a spinner like the one that follow, where 3/5 of the spinner is red, 1/5 is blue and 1/5 is yellow. elibri earns 15 points every time she spins a blue of yellow space, and she earns 5 points every time she spins a red space. what is the expected value of a single spin?and you

The expected value is the sum of values multiplied by their probabilities.

... 15×(1/5+1/5) + 5×(3/5) = 6+3 = 9

The expected value of a single spin is 9 points.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
