A, B , and C are collinear points: B is between A and C. If AB = 36, BC = 5x - 9 , and AC = 54 , find x
balandron [24]

9514 1404 393

Answer:

  x = 5.4

Step-by-step explanation:

The segment sum theorem tells you ...

  AB +BC = AC

  36 +(5x -9) = 54

  5x = 27 . . . . . . . . . . . subtract 27 from both sides

  x = 5.4 . . . . . . . . . . divide by 5

Estimate the area of a circle with a radius of 16 meters. Use 22/7 or pi
Dmitrij [34]
1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:

22/7(16^2) = about 805 meters squared.

2. Let's find the area of the rectangle first.

A=LW
A= 18(10)

A= 180 cm squared.


Now the semi-Circle:

The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:

22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:

127 cm squared for the semi-circle.

Now we add up the rectangle and semi-circle's areas:

180 + 127 = 307 cm squared as your answer.


I hope this Helps!
