Circumference of a Circle,C=2πr
π=3.14
r= of the circle
Area of the circle= πr²
We know that
Area= 49 π²
πr²=49
r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units
Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units
5×.98 is 4.90 then add 19.29 and add 14.25. this equals $38.44 hope this helps.
Answer:
x = 4 root square 3
Step-by-step explanation:
sin60° = x/8
x = 8×sin60° = 4 root square 3
4 - (-13) = 17
Hope this helps!
Answer:
Step-by-step explanation:
Find the slope = -2/1
Find the y-intercept = 5
Go to graph
put a dot at (0,5)
since it's a negative slope you will go up 2 and left 1
draw your line
_________________________________________________
Find the slope = 3/1
Find the y-intercept = 0
go to graph
Put a dot at (0,0)
Since it is a positive slope you will go down 3 and left 1.
To find the slope and y-intercept use this formula=
y=mx+b
m=slope
b=y-intercept
I'm sorry I don't know how to do a check equation for these.
