A25-inch wide drum is used in a marching band. what area does the top of the drum cover? round to the nearest hundredth. (use 3.14 for pi.)

Hello from MrBillDoesMath!

490.87 square inches

Discussion:

We are given that

d = 25                                  => As d(iameter) = 2 * r

2r = 25                                 => divide both sides by 2

r =  25/2 = 12.5

The area of a circle of radius "r" is Pi * r^2. Plugging in our specific numbers gives

A = Pi * (12.5)^2

  = (3.1415) * (156.25)       approximately

 =  490.87

Thank you,

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
