Question

1. find the area. use 3.14 for pi and round your answer. a circle with diameter 22 cm is shown

Explanation:

Step1: Calculate the radius

The radius $r$ is half the diameter.
$r = \frac{22}{2} = 11$ cm

Step2: Apply area formula of circle

Use $A = \pi r^2$, substitute $\pi=3.14$, $r=11$.
$A = 3.14 \times 11^2 = 3.14 \times 121$

Step3: Compute final area

Calculate the product and round.
$A = 379.94$

Answer:

379.94 square centimeters
