Answer: The diameter of Pool A is 7.32 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.
Step-by-step explanation:
The diameter of a circle is double its radius.
Pool A has a radius of 12 feet - double that would be 24 feet, its diameter.
Next, convert this to meters:
[tex]24 * \frac{0.305}{1} = 7.32[/tex]
The diameter of pool A is 7.32 meters.
The diameter of pool B is 7.5 meters.
The diameter of pool B is greater.
You can calculate the circumference of a circle by using this formula:
[tex]C = 2\pi r[/tex], where r is the radius.
Divide 7.5 by 2 to get your radius of Pool B, which is 3.75, and solve for C:
[tex]C = 7.5\pi \\\\C = 23.561[/tex]
Rounding to the nearest hundredth, the circumference for pool B is 23.56 meters.
Do the same thing for pool A:
[tex]C = 7.32\pi \\\\C = 22.996[/tex]
Circumference for pool A rounds to 23 meters.
