h = 36
Pp = ?area of a circle
l = ? surface of the wheel
Pb = lateral surface
Pc - total surface
Pp = πr² = 9²*π = 81π (unit²)
l = 2πr = 2*9*π = 18π (unit)
Pb = l*h = 18π * 36 = 648 π(unit²)
Pc = 2Pp + Pb = 2* 81π + 648π = 162π + 648π = 810π(unit²)
Answer total area equal to 810π (unit²)
I will put the SA formula for btoh
SAcylinder=2pir^2+2hpir
2pir^2=2 bases
2hpir=around area
r=9
h=36
SA=2pi9^2+2*36pi*9
SA=2pi81+72pi9
SA=162pi+648pi
SA=810pi
aprox pi=3.141592
SA=2544.68952 in^2

Given:
54 miles long highway
5 3/5 miles constructed per month.
Will the highway be finished in 8 months?
5 3/5 ⇒ ((5*5)+3)/5 = 28/5
28/5 * 8/1 = 28*8 / 5*1 = 224/5 = 44.8 miles or 44 4/5 miles
No. The highway can not be finished in 8 months. Only 44.8 miles or 44 4/5 miles will be constructed by that time.
54 ÷ 28/5 = 54 * 5/28 = 54*5 / 28 = 270 / 28 = 9.64 months or 9 18/28 or 9 9/14 months must be spend to complete the highway.
