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
Hey there! :)
You have to use the Pythagorean Theorem ⇒ a² + b² = c²
a = 5
5² = 5 × 5 = 25
b = 13
13² = 13 × 13 = 169
169 + 25 = 194
√194 = 13.93
That means McKenzie is correct and Cara is wrong ; c = 13.93
Hope this helps :)

Answer:
y = 1/2x -2
Step-by-step explanation:
The 2-point form of the equation for a line is useful for answering questions like this.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . equation of a line through (x1, y1) and (x2, y2)
Filling in the given points, the equation becomes ...
y = (-4 -(-5))/(-4 -(-6))/(x -(-6)) -5
y = 1/2(x +6) -5
y = 1/2x -2
