Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
I think a. But I don’t understand this question.
X=4,,,,,,,,,,,,,,,,,,,,,,,,,,y=1,,,,,,,,,
Combine (5-i)+3i
Your answe would be a>-2 so just plug that in to the line and that will be your answer which is the second one
