A sphere has a surface area of 9,244 square feet.
What is the radius of the sphere? Round
to the nearest hundredth.

The answer to your question is radius = 27.1 ft

Step-by-step explanation:

Data

Surface area = 9244 ft²

radius = ?

Process

To solve this problem, look for the formula of surface area, substitute values and simplify.

1.- Formula of the area of a sphere

    Surface area = 4π r²

2.- Solve for r²

     r² = Surface area / 4π

3.- Substitution

     r² = 9244 / 4(3.14)

4.- Simplification

     r² = 9244/12.56

     r² = 735.98

5.- Result

     r = 27.1 ft

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.
