All the members of a construction crew work at the same pace. four members of the crew, working together, are able to pour foundations in 32 hours. a how many hours would this job take if there were half as many workers?

Half of 4 is 2 so set up a proportion using 4, 32, and 2.

Then, cross multiply and solve for y.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
