Answer:

Area: 96 x pi

Perimeter: 8 x pi

Step-by-step explanation:

Area: the shaded part is 1/3 of the circle and is 120 degrees of the 360 degrees of the circle

use the area formula: r^2 x pi x 120/360

plug in r=12 and you should get 96 pi

Perimeter: the formula for circumference is 2 x pi x r x 120/360

plug in r=12 and you should get 8 x pi

Answer:

Step-by-step explanation:

Distance traveled in $1\frac{4}{5}$ hours = $\frac{3}{10}$

Distance traveled in 1 hour = $\frac{3}{10}$ ÷ $1\frac{4}{5}$

$=\frac{3}{10}$ ÷ $\frac{9}{5}$

$= \frac{3}{10}*\frac{5}{9}\\\\=\frac{1}{2}*\frac{1}{3}\\\\=\frac{1}{6}$

distance traveled in 3 1/5 hours = $\frac{1}{6}*3\frac{1}{5}$

= $=\frac{1}{6}*\frac{8}{5}\\\\=\frac{1}{3}*\frac{4}{5}\\\\=\frac{4}{15}$
