Janna is making a prediction of the frequency of a key that is 12 keys from middle c.
which best describes her prediction?
interpolation, because a key that is 12 keys from middle c is within the data set
interpolation, because a key that is 12 keys from middle c is outside the data set
extrapolation, because a key that is 12 keys from middle c is within the data set
extrapolation, because a key that is 12 keys from middle c is outside the data set

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.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
