Question

find the circumference and area of the following circle. a circle with a diameter of 19 feet the circumference is approximately (round to the nearest tenth as needed.)

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter. Here, \( d = 19 \) feet.
\( C=\pi\times19 \)

Step2: Calculate the circumference

Using \( \pi\approx3.1416 \), we have \( C\approx3.1416\times19 \)
\( 3.1416\times19 = 59.6904 \)

Step3: Round to the nearest tenth

Rounding \( 59.6904 \) to the nearest tenth gives \( 59.7 \).

For the area:

Step1: Recall the formula for area

The formula for the area \( A \) of a circle is \( A=\pi r^{2} \), where \( r \) is the radius. The radius \( r=\frac{d}{2}=\frac{19}{2} = 9.5 \) feet.
\( A=\pi\times(9.5)^{2} \)

Step2: Calculate the area

\( (9.5)^{2}=90.25 \), so \( A = \pi\times90.25\approx3.1416\times90.25 \)
\( 3.1416\times90.25 = 283.5289 \)

Step3: Round to the nearest tenth

Rounding \( 283.5289 \) to the nearest tenth gives \( 283.5 \).

(If only circumference is needed as per the initial box, here is the circumference part)

Answer:

The circumference is approximately \( 59.7 \) feet. The area is approximately \( 283.5 \) square feet. (If only circumference is required, then just \( 59.7 \) feet)
