3 days would take the 15 workers to finish the same task

Step-by-step explanation:

Let us use this relation to solve the question

∵ 5 workers can complete a certain task in 9 days

∴ N = 5 workers and T = 9 days

→ By using the relation above

∴ 5 × 9 = k ⇒ (1)

∵ If there are 15 workers will make the same task

∵ They can finish it in x days

∴ N = 15 workers and T = x days

→ By using the relation above

∴ 15 × x = k ⇒ (2)

∵ k is the same task, then equate the left sides of (1) and (2)

∴ 15 × x = 5 × 9

∴ 15x = 45

→ Divide both sides by 15 to find x

∴ x = 3 days

∴ 3 days would take the 15 workers to finish the same task

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
