question
the radius of a circle is 19 ft. find its area in terms of π.
answer attempt 1 out of 2
a=
ft²
submit answer
π

Explanation:

Step1: Recall the formula for the area of a circle

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

Step2: Substitute the given radius into the formula

Given \(r = 19\) ft. Substitute \(r = 19\) into \(A=\pi r^{2}\), we get \(A=\pi\times(19)^{2}\).

Step3: Calculate \((19)^{2}\)

\((19)^{2}=19\times19 = 361\).

Answer:

\(361\pi\)
