What is the area of a circle with a diameter of sixteen meters? Use twenty-two sevenths for pi.

one hundred eighty-four and six-sevenths meters squared
one hundred eighty-eight meters squared
two hundred one and one-seventh meters squared
two hundred four and two-sevenths meters squared

Answer 1

If the diameter is 16, the radius is 8 because it is half of the diameter. You can use the equation\[A=(\pi)r ^{2}\]
Just plug in the values you know.
\[A=(\frac{ 22 }{ 7 })(8)^{2}\]

(I'm sure on this one. I have the equations for the right this time.)

Answer 2

i still dont get it i did 22/7 times 8 and got 25.14

Answer 3

Square the 8 first.

Answer 4

so i do 64 x 22/7

Answer 5

oh thanks

Answer 6

Yep! You'll multiply 22*64 and then put it over 7.
