Answer:
r = 45 m.
Step-by-step explanation:
pi r^2 = 6358.5
r^2 = 6358.5 / pi
r = √(6358.5 / pi)
= 44.989 m
Answer: 210 advanced tickets were sold. 130 same day tickets were sold.
Step-by-step explanation:
x= advanced tickets y=same day tickets
2x+3y=810 this equation represents the money
x+y=340 this equation represents the total number of tickets
x+y=340
<u>-x -x</u>
y=-340-x 2x+3(340-x)=810 210+y=340
2x+1020-3x=810 <u> -210 -210 </u>
-x+1020=810 y=130
<u> -1020 -1020</u>
<u>-x</u>=-<u>210</u>
-1 -1
x=210
Answer:
radius = 10
Step-by-step explanation:
The distance from the centre to the point on the circle is the radius r
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (1, - 2) and (x₂, y₂ ) = (- 5, 6)
r = 
= 
= 
= 
= 
= 10
