Question

find the area of a circle with a radius of 8. either enter an exact answer in terms of \\(\pi\\) or use 3.14 for \\(\pi\\) and enter your answer as a decimal. units\\(^2\\) show calculator

Explanation:

Step1: Recall circle area formula

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

Step2: Substitute radius $r=8$

$A = \pi (8)^2 = 64\pi$

Step3: Calculate decimal approximation

Using $\pi=3.14$, $A = 64 \times 3.14 = 200.96$

Answer:

Exact answer: $64\pi$ units$^2$
Decimal answer: $200.96$ units$^2$
