Question

the radius of a circle is 19 inches. what is the circles area?
round your answer to the nearest hundredth.
square inches

Explanation:

Step1: Recall circle area formula

The area of a circle is given by $A = \pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 19$ into the formula:
$A = \pi (19)^2$

Step3: Calculate the squared radius

$19^2 = 361$, so $A = 361\pi$

Step4: Compute numerical value

Use $\pi \approx 3.14159$:
$A \approx 361 \times 3.14159 = 1134.11399$

Step5: Round to nearest hundredth

Round $1134.11399$ to two decimal places: $1134.11$

Answer:

1134.11 square inches
