Explanation:

The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (

160

meters).

To find the circumference of the circle, we need to know the diameter.

Circumference of a circle:

d

π

or

2

r

π

, where

d

represents diameter and

r

represents radius

The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is

14400

and that its length is

160

.

Width: area divided by length

14400

160

=

90

The diameter of the circle and the width of the rectangle is

90

meters.

Circumference:

90

⋅

π

=

90

π

→

If you are using an approximation such as 3.14 for

π

, multiply that by 90

Add

160

⋅

2

to the circumference since the lengths of the rectangle are also part of the perimeter.

160

⋅

2

=

320

90

π

+

320

What is the length of pr ? PLEASE HELP
Karolina [17]
The angles in the triangles are the same, so you know the triangles are similar. Sides PQ and AB correspond as do sides PR and AC. Because the triangles are similar, you know that
  PR/AC = PQ/AB
  PR/24 = 5/20
Multiplying this equation by 24 gives
  PR = 24*(5/20) = 6

The appropriate choice is ...

What equation is equivalent to 3(a+4)-5(a-2)=22?
Nata [24]

Answer:

a = 0

Step-by-step explanation:

=> 3(a+4)-5(a-2) = 22

Opening Brackets

=> 3a+12-5a+10 = 22

=> 3a-5a+12+10 = 22

=> -2a+22 = 22

Subtracting 22 to both sides

=> -2a = 0

Dividing both sides by -2

We get,

=> a = 0
