A50-centimeter piece of wire is bent into a circle. what is the area of this circle?

Step-by-step explanation:

Circumference of circle = length of the wire

                        2πr = 50 cm

2 * 22/7 * r = 50

       2*22*r = 50*7 = 350

r = 350 / 2 * 22

r = 175/22 cm

Area of the circle = πr²

             = 22/7 * (175/22)²

             = 22 * 175 *175 / 22 *22 *7

              = 175 * 175/22*7 = 25 * 175 /22

             = 4375/22

             = 198.86 cm²

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
