Area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: ( 3 , − 1 )
Equation Form: x = 3 , y = − 1
(I hope it helps ♡＾▽＾♡)
9+4+7+3+10+9=42
42÷6= 34.5. I believe "mean" is the same as avgerage.
Answer:
6 yds
Step-by-step explanation:
7 + 3 = 10
christine: 7/10ths of ribbon
0.7(20)=14 yds
kaylani: 3/10ths of ribbon
0.3(20)=6 yds
The equation that works for this is
y=1/7x + 0! It is parallel and goes through (0,0)
Hope this helps :)
