Answer:
11,880π in^3
Step-by-step explanation:
The volume of a cylinder = π r^2 h
Large Cylinder V = π * 15^2*40 = 9,000π in^3
Small Cylinder V = π * 12^2 * (60-40) = 2880π in^3
Adding: the total volume of the model = 11,880π in^3
There were 7.7 million families with dependent children in the UK in 2012, 1 in 7 of which had three or more dependent children. Married couples had a higher average number of dependent children in their family than other family types, at 1.8 children per family compared with 1.7 on average.
