Question

The surface area of the top surface of the water in a circular swimming pool is about 206 square feet. Estimate the radius of the pool, to the nearest foot.

Answer 1

\[A=\pi R^2\]
\[\sqrt{\frac{A}{\pi}}=R\]

Answer 2

so do you take 260/ 3.14?

Answer 3

260/ 3.14~86

now the square root of that, is a bit more than the square root of 81 which is nine

Answer 4

there is no answer of 9 gosh i dont get this at all

Answer 5

ops the area is 206, not 260

Answer 6

Answer 7

(206/3)~68.7
the square root of that is a bit more than the square root of 64 ie 8

Answer 8

so the pool has a radius of a little bit more than 8ft

Answer 9
