Question

compute the area of a circle with a diameter of 19 inches. you do not need to include the unit measurement or unit type. only the numerical answer is necessary. round to the nearest tenth if necessary. use the value of 3.14 for pi.

Explanation:

Step1: Find the radius

The radius \( r=\frac{d}{2} \), where \( d = 19 \). So \( r=\frac{19}{2}=9.5 \)

Step2: Calculate the area

The formula for the area of a circle is \( A=\pi r^{2} \). Substitute \( \pi = 3.14 \) and \( r = 9.5 \) into the formula: \( A=3.14\times(9.5)^{2}=3.14\times90.25 = 283.385 \)

Answer:

283.4
