Step-by-step explanation:
circumference =pi × diameter
=(22/7)×2.2
=6.914ft
Answer:
6.91 feet
1.6022x 10-19
1.6022x 10-19 then simplifies into 16.022 because of the 10, and then the final answer is -2.978
y=4
Solve the second equation for y
Substitute the given value of y into the first equation
Solve the equation for x
Substitute the given value of x into the second equation
Solve the equation for y
The possible solution of the system is the ordered pair (x,y)
