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,

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
