Question

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

Answer 1

3.14 of 100 =314 that the answer

Answer 2

Answer:

$78.5yd^{2}$

Step-by-step 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.

$A=3.14*(5yd)^{2} \\A=3.14*25yd^{2} \\A=78.5yd^{2}$
