  1. (d) 151 in

  2. (a) 43.3 in

Step-by-step explanation:

1. The circumference is ...

  C = 2πr

  C = 2(3.14)(24 in) = 150.72 in

  C ≈ 151 in

__

2. C = 2πr

  r = C/(2π) = 272.2 in/(2·3.14) ≈ 43.3439 in

  r ≈ 43.3 in

1.Option 4

2.option 1

Step-by-step explanation:

1.circumference of circle=2πr=2π×24=48π or 151in

2.circumference of circle=2πr

272.2=2πr

r=272.2/(2π)=43.3in

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

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.
