The diameter of a circle is 3 cm. Find its area to the nearest tenth. A=A=
\text{ cm}^{2} cm
2

Step-by-step explanation:

diameter = 3 cm

radius = 3/2 = 1.5 cm

Area of circle = πr²

                      = 3.14 * 1.5 *1.5

                       = 7.065

                      = 7.1 square cm

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
