A cylindrical container contains some sand as shown below. How much more sand must be added for the container to be half full? Use 3.14 for pi. 785 cubic inches

392.5 cubic inches

235.5 cubic inches

157 cubic inches

785 cubic inches

Step-by-step explanation:

2πR + 2πR is the equation.

2π(5)^2 + 2π(5)(10)

50π + 200π

250 (3.14)= 785 inches cubed

I strongly believe this answer is correct, hope it helps.

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.
