Explain step by step I see on getting about 41 but theres nothing that equals that

Answer 1

$\text{Area \ of \ sector} = \frac{\theta}{2}*r^2 \ \ \ [\theta= \text{central angle in radians, r=radius} ] \\ \\ A= \cfrac{\frac{5 \pi }{3}}{2}*8^2= \cfrac{5 \pi }{3*2}*64= \cfrac{5 \pi }{3}*32=\cfrac{160 \pi }{3} \ \ \ \text{units}^2$
