r = 18 ÷ 2 = 9

area of semicircle = πr²/2

area of semicircle = 3.142 . 9²/2

area of semicircle = 3.142 . 81/2

Step-by-step explanation:

we know ,

area of circle =πr^2

hence we get from the figure that the diameter of circle is 19 cm and we can find radius

r=d/2

r=18/2=9cm

area of semicircle =πr^2/2

area of Semi circle equals to =22*(9)^2/7/2

=127.2857143

What is the y-coordinate of the solution of the system of equations? {y=3x−262x−y=19
givi [52]

Answer:

<h2>           y = -5</h2>

Step-by-step explanation:

y = 3x − 26

2x − y = 19

2x - (3x - 26) = 19

2x - 3x + 26 = 19

   - x = - 7

     x = 7

y = 3•7 -26 = 21 - 26 = - 5
