Question

A Circular above ground swimming pool has a radius 3 metres and contains water to a uniform depth of 0,9 meters.

a) what is the valume of water in the pool? Answer in cubic metres correct to 1 decimal places.

b) How many litres of water are in the pool (1 m *3= 1000L) answer correct to the nearest litre.

Thank u if you answer this question!! U are amazing!!

Answer 1

r=3 m

d=.9m

V=pi(r^2)d = pi(3)^2(.9) = 8.1pi m^3 = about 8.1(3.14159) = about 25.447 = about 25.4 m^3

= about 1000(25.447) = about 25,447 liters
