Question

Consider two circular swimming pools. Pool A has a radius of 28 feet, and Pool B has a diameter of 17.26
meters. Complete the description for which pool has a greater circumference. Round to the nearest
hundredth for each circumference. 1 foot-0.305 meters

Answer 1

Answer:

Pool B has the greater circumferance.

Step-by-step explanation:

Pool B- As the diameter is the length of the horizontal line across the centre of the circle, and in order to calculator the circumferance, we need the radius, we can divide 17.26 by 2.

Circumferance formula: 2πr

Radius: 8.23m     Circumferance= 54.22m

Pool A- Already has the radius, 28 feet, so all we need to do is apply the formula to get 175.93ft.

However the units of measurement are different, so we must convert the ft to metres (or visa versa) 0.3048m is approximately 1ft, we can plug this into a converter to get 53.623464m for pool a. To get this manually, you multiply 175.93 by 0.305
