Question
Find the perimeter of the figure to the nearest hundredth. pls help

50.26 in

Step-by-step explanation:

First you need the circumference of half of a circle.

Circumference = diameter x pi. The radius is 9, so the diameter is 18. 18 * 3.14 = 56.52. But you need half of that, so 56.52 / 2 = 28.26

Then add the other 3 sides

28.26 + 5 + 12 + 5 = 50.26

They need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases

Step-by-step explanation:

Let x be the no. of pairs of uniform pants  for which the total cost in both the cases will be same.

Case 1:

Cost of 1 pairs of uniform pants = $17.95 each

Cost of x pairs of uniform pants = $17.95x

Cost of sweater = $24.

Total cost = 24+17.95x

Case 2:

Cost of 1 pairs of uniform pants = $18.95

Cost of x pairs of uniform pants = $18.95x

Cost of sweater = $18

Total cost = 18+18.95x

ATQ

Hence they need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases
