At the end of the school year, rachel and amber go to the roof of a 12-story building and throw their algebra book off the edge. the equation of the pathway that each girl's textbook takes is given below. by how many seconds does rachel's textbook beat amber's to the ground?

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
