When a wire is bent to form a circle then its length represents the circumference of the circle formed. Therefore in our case the circumference of the circle is 50 cm. we can use this to determine the radius of the circle and then determine the area. Circumference of a circle is given by \pi × diameter, (\pi = 3.142)
thus diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
the radius will be 15.9134 ÷2 = 7.9567 cm or ≈ 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Thus the area of the circle formed is ≈ 199.08 square cm ( 2 decimal places)

Answer:
36% of 240
=36/100*240
=6640/100
=86.4
Step-by-step explanation:
You can rewrite this as A - 25 = 75. You always can cancel adding a negative into just subtracting, and although it may not seem important yet, it’s a good habit to get into for further algebra.
A = 100.
