. Correct option is D) 113.0 ft² .
<u>Step-by-step explanation:</u>
Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:
We know that area of circle = 
, We have following parameters as
So , Area of circle is
⇒ 
⇒ 
⇒ 
⇒ 
On Rounding off
⇒
Therefore , . Correct option is D) 113.0 ft² .
Inverse variation is of the form:
y=k/x, which we can express as:
yx=k we are given the point (2/3, 7) so we can solve for k
7(2/3)=k
14/3=k
y=14/(3x), so when x=7/3
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2
I hope this helps you
x^2-x-72=0
x -9
x +8
(x-9)(x+8)=0
x=9
x= -8
