Find the volume of the cone. What is the radius?
12

What is the height?
5

Write the volume in terms of pi (1/3 times radius squared times the height only).
π km3

Solve for the volume (Multiply by 3.14 this time)

Step-by-step explanation:

Your first two answers are incorrect. Radius = 5 km

Height = 12 km

volume of cone = πr²h/3 = π5²⋅12 = 300π km³

300π ≈ 942 km³

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.
