Question

the radius of a circle is 7.9 yards. what is the circle’s area? round your answer to the nearest hundredth. square yards

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 $r = 7.9$ yards into the formula:
$A = \pi (7.9)^2$

Step3: Calculate $7.9^2$

$7.9^2 = 62.41$

Step4: Compute the area

$A = \pi \times 62.41 \approx 3.1416 \times 62.41 \approx 196.07$

Answer:

196.07 square yards
