I think the answer should be 10π+ 10m2, because there is 2 semi-circles and one rectangle , and the rule to find area of a rectangle is length x width and the area of a semi-circle is πr2/2, I hope that helps
Fifirst one is C becuase of the formula c=2peiR and you solve for pei
2 1/3 x 9=(2+1/3) * 9=(2*3+1)/3 * 9=7/3 * 9=63/3=21
Answer: 2 1/3 x 9 = 21
Answer:
40
Step-by-step explanation:
The value of a right angle is 90° and <SQR is a fraction of <PQR.
Hence, <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.
Or we can do it like this;
⇒ 180-90-50
⇒ 90 - 50
⇒ 40
Thus, Answer is 40.

Is it supposed to say 7x rather than Z? If so then
If you make both equations = to 4y you can work out the answer so
4y =7x-4
4y = 36-3x
Then you put them equal to each other so
7x-4 = 36-3x
10x = 40
x = 4
You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6
So the answer is x = 4 and y = 6
