Question

A circles diameter is 10 yards what is the circles area using 3.14

Answer 1

`78.5yd^(2)`

Explanation:

The formula to find the area of a circle of is: A =
`\pi r^(2)`

However, the question wants to use 3.14 instead of pi.

We need to find the radius. The radius of the circle is half the diameter. So, the radius to 5 yards.

Now we just plug in the formula.

`A=3.14*(5yd)^(2) \\A=3.14*25yd^(2) \\A=78.5yd^(2)`

Answer 2

3.14 of 100 =314 that the answer
