Answer:
48π + 120
Step-by-step explanation:
Lateral area of a cylinder = Ch = πdh
1/4 of the lateral area = 12π(10)/4 = 30π
Bottom area = 6(10) = 60
Front area = 6(10) = 60
Area of base = πr^2/4 = 36π/4 = 9π
Area of two bases = 18π
Total area = 18π + 30π + 60 + 60 = 48π + 120
2x²+13x-45 =(x+9)(2x-5)
3/(x+9)=[3(2x-5)]/[(x+9)(2x-5)]=(6x-15)/(2x²+13x-45)
For this rectangle 2 sides are 4 units and the other 2 are 2 units long. 4+4+2+2=12 and 4 times 2= 8
