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, you can use the formula:

\[ \text{Area} = \pi r^2 \]

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

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

Now, substituting the radius into the area formula, we have:

\[ \text{Area} = \pi (8)^2 \]

Calculating \( (8)^2 \):

\[ (8)^2 = 64 \]

Now multiply by \( \pi \). Using \( \pi \approx 3.14 \):

\[ \text{Area} \approx 3.14 \times 64 \]

Calculating that:

\[ 3.14 \times 64 = 200.96 \]

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

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