Answer:

a

Step-by-step explanation:

Cylinders:

Ratio of radii = 1 : 4

Radius of two cylinders are: r , 4r

Ratio of height = 3 :1

Height of two cylinders are: 3h , h

Lateral surface area of cylinder =  2πrh

Ratio of lateral surface area= 2π* r * 3h   : 2π* 4r * h

                                             = 3 : 4

Help me please im beggingggg

Answer: <u>96</u> sq ft.

Step-by-step explanation:

      First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.

             A = L * W

             A = (10 ft) * (3 ft)

             A = 30 ft²

             30 ft² * 3 = 90 ft²

      Next, we will find the area of the two triangles.

             A = \frac{b*h}{2}

             A = \frac{3*2}{2}=\frac{6}{2} =3

             3 ft + 3 ft = 6 ft²

      Lastly, we will add them together for the total surface area.

90 ft² + 6 ft² = 96 ft²
