Answer:
d=14.5
r=14.5/2=7.25
area=4πr^2=3.14×7.25×7.25=165.04 inches sq
It’s 16 look at it a bit closer if you get confused step away and clear your mind a bit
The one all the way to the left matches with 1/7
1/18 matches with 0.05
0.5 matches with square root of 0.25
2/3 matches with 0.6
That's all I can help with.
We have that
(r, ∅)----------> (-7, <span>5 pi/3)
we know that
</span>5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
