Answer:

44 units

Step-by-step explanation:

The tangents from an external point to a circle are congruent, then

perimeter = (9 + 9) + (8 + 8) + (13 - 8 ) + (13 - 8)

= 18 + 16 + (5 + 5)

= 18 + 16 + 10

= 44 units

Name of a ray. <br>1.02 points, lines, planes Vocabulary Quiz<br>

TEA [102]

Answer:

Lines. A ray is a line that originates from a point till infinity.

Step-by-step explanation:

A ray is a form of a line, but it has a starting point. It starts from a point, and extends till infinity in a given or required direction.

This property distinguish completely a ray from a line or segment. Lines extends to infinity in both its directions. And a segment is the length of a line between its starting point and end point.

Thus, we can say that rays are special forms or types of lines.

The area of the figure. Use 3.14 for pie

balu736 [363]

Answer:

54.5 $ft^{2}$

Step-by-step explanation:

divide it to one rectangle and two different triangles.

Rectangles area: (8+3)*4 = 44 $ft^{2}$

triangle top: 4*3/2 = 6 $ft^{2}$

triangle bottom: 3*3/2= 4.5 $ft^{2}$

sum the all up: 44+6+4.5 = 54.5 $ft^{2}$

don't know how to do it with π though if that's obligatory
