Question

I need help with this one...

Consider two circular swimming pools. Pool A has a radius of 32 feet, and Pool B has a diameter of 19.7 meters. Complete the description for which pool has a greater circumference. Round to the nearest hundredth for each circumference. 1 foot ≈ 0.305 meters



The diameter of Pool A _____ is meters. So, the diameter of Pool _____ is greater, and the circumference is _____ by _____ meters

Answer 1

Pool A is 61.3 meters.
Pool B is 75.5 meters.


Explanation:
To find the circumstance, the equation is c=2(pi)(r).
So for pool A 2•3.14•32=201 Ft. but then you times 201 by .305 and you get 61.3 meters
Since pool b doesn’t give you a radius, you’ll have to find it. Which a diameter is just half a circle and the radius is the full so you times the diameter by two to find the radius. So the radius is 39.4. So for pool B it’s 2•3.14•39.4=247ft which times by .305 and you get 75.5.
