Answer: x=6,y=4
Explanation:
x + y = 10 x − y = 2
Add both equations together.
x + x + y − y = 10 + 2
2 x = 12∣ : 2
x = 6
Sub the result into any of the two equations for x
6 + y = 10∣− 6
y = 4

Answer:
415.27in^2
Step-by-step explanation:
area of a circle is
a= pi(r)^2
the radius is half of the diameter so you would do 23/2 = 11.5 for the radius
a= 3.14 (11.5)^2
= 3.14 x 132.25
= 415.27 inches^2
