Answer: $ 10,988.25 
Step-by-step explanation:
Hi, to answer this question, first we have to multiply the original number of students scheduled to go to the trip (420) by the added students’ percentage (15%) in decimal form (divided by 100)
420 x (15/100) = 420 x 0.15 = 63 students added
Adding the number of extra students to the original number:
420+63 = 483 students (total number of students)
Finally, we have to multiply the result by the cost of each admission ticket (22.75)
483 x 22.75 = $ 10,988.25

Step-by-step explanation:
I assume you mean 
there is a common factor of 9 in the numerator and denominator so we can cancel out to form  
 
 is technically a correct answer, but I will go ahead to rationalize the denominator

Answer: 308cm
Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr. 
So, 
2πr (circumfrence)= 44cm. 
Height= 7cm. 
2πr × h = 44 x 7 = Curved surface area. 
Curved surface area= 308cm
