Really trying to pass this exam and graduate can someone smart me with these problems im running out of time ..

1172.08 square inches

Step-by-step explanation:

Total surface area is area of all the surfaces.

Cylinder:

Top surface = πr^2 = π(4)^2 = 16(3.14) = 50.24

Lateral Surface = 2πrh = 2π(4)(9) = 72π = 72(3.14) = 226.08

Rectangular Prism:

2 sides = 2*(11*11) = 242

front and back = 2*(16*11) = 352

bottom = 16 * 11 = 176

Top part (it is top rectangle - bottom of cylinder) = (16*11) - (π(4)^2) = 125.76

Adding all up, we get:

50.24 + 226.08 + 242 + 352 + 176 + 125.76 = 1172.08 square inches

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
