Question

What is the area of a circle with a diameter of 16 maters? use 22/7 for pi.

Answer 1

22/7*8^2

Answer 2

Why would you use 22/7 for pi?!? Just use pi!

Answer 3

RIGHT!!??!!??!!??!!??!!

Answer 4

22/7 is approximate of pi

Answer 5

so wats the answer.

Answer 6

The area of a circle is \[\pi \times r^2\],
And the radius is half the diameter (thus, 8)
\[22/7 \times 8^2 = ~201.142848\]

Answer 7

There is no reason to approximate it. Certainly not with a ratio..

Answer 8

\[r = 8 \implies Area = \pi (8^2) = 64\pi \]

Answer 9

HELP!!!!

Answer 10

Just tell me the answer

Answer 11

If you don't want it approximated, that's 1408/7, or 201 1/7
