What is the area of a circle with a diameter of 16 yards? Estimate the area to the hundredths place using 3.14 for π .

1 answer

To find the area of a circle with a given diameter, we can use the formula for the area of a circle:

\[ A = \pi r^2 \]

where \( r \) is the radius of the circle. The radius is half of the diameter. Given that the diameter is 16 yards, the radius is:

\[ r = \frac{16}{2} = 8 \text{ yards} \]

Now, we can substitute the radius into the area formula using \( \pi \approx 3.14 \):

\[ A = 3.14 \times (8)^2 \]

Calculating \( (8)^2 \):

\[ (8)^2 = 64 \]

Now substitute this back into the area formula:

\[ A = 3.14 \times 64 \]

To calculate \( 3.14 \times 64 \):

\[ A = 200.96 \]

Thus, the area of the circle, estimated to the hundredths place, is:

\[ \boxed{200.96} \text{ square yards} \]
