Answer:199

Explanation:

the formula for the area of a circle is
\pi r^(2) (pi *radiusto the power of 2)

so the 50 metered wire is the circumference of the circle

to get the area of the circle you need the radius

to get the radius you need to divide 50 by 3.14 (
\pi), that equals to 15.923566879 this is the diameter to get the radius you need to divide it by 2 . radius =7.961783439

formula for area =
\pi r^(2)


\pi=3.14

3.14ˣ7.961783439ˣ7.961783439=199.044585975

round it to nearest number = 199

Answer:

199 cm^2

Explanation:

1. First, we have to find the radius. Divide the circumference by pi (3.14): 50/3.14=15.92. This gives us the diameter.

2. Divide the diameter by 2: 15.92/2=7.96. This is the radius.

3. Use the formula for the area of a circle. Area=3.14*7.96^2.

4. Solve this equation and you get the answer: About 199 cm^2
