3 0

Answer:

r = 2cm

h= 18cm

surface area of cylinder = 2πr ( r + h)

                                          = 2*22/7*2(2+18)

                                          = 125.714cm²

volume of cylinder = πr²h

                               22/7*(2)²*18

                             =226.29cm³

Oksi-84 [34.3K]

Answer:

<em>Bree spoke at 55 assemblies in this district.</em>

Step-by-step explanation:

Bree speaks at school assemblies charging a school district a total cost C modeled by the equation:

C(a) = 50a+1,500

Being a the number of assemblies attending the meeting.

It's given Bree charged the Escambia City School District $4,250  to speak at school assemblies.

We can find the number of assemblies by solving the equation:

50a+1,500=4,250

Subtracting 1,500:

50a=4,250-1,500=2,750

Dividing by 50;

a = 2,750 / 50=55

Bree spoke at 55 assemblies in this district.
