6 3/4 would be your answer
Step-by-step explanation:
Solution,
Area=38.5 cm²
by using the formula of are of a circle i.e, πr², we get
πr²= 38.5 cm², where π=22/7
r²=38.5 cm²/π
r²=12.25 cm²
r=√12.25 cm²
r=3.5 cm
Now, by using the formula of circumference of a circle i.e, 2πr, we get
2πr=2×π×3.5 cm, where π=22/7
=22 cm
So, the circumference of the circle is 22 cm.

Answer:
-0.5
Step-by-step explanation:
The average rate of change from a to b:
[f(b) - f(a)]/(b - a)
Look in the graph for the function values at x = -3 and x = 0.
f(-3) = 2
f(0) = 0.5
average rate of change =
= [f(-3) - f(0)]/(-3 - 0)
= [2 - 0.5]/(-3)
= 1.5/(-3)
= -0.5
-46=3x+7x
-46=10x
X= 10/(-46)
X=-5/23
Therefore, the equation only has one solution
