Find the area of a circle with a radius of 3

A≈28.27

is pi × r^2 with pi = 3.141592653589793

Therefore, the area depends only on the size of r. That is why you only need to enter r here to get the area

The calculator will only accept positive value for r since a distance cannot be negative

if r = 3 cm for instance,

area = 3.14 × 3^2 = 3.14 ×9 = 28.27 cm

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
