a circle has a radius of 2x inches. if the radius is multiplied by a factor of 3/8. what is the new area of the circle

(PI x 3/4x square) inches

Step-by-step explanation:

A of a circle = pi times radius squared

A = pi times 3/4x - that is 2x times 3/8

A = 3.14 (or whatever you use for pi) x 3/4 x inches square

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.
