Answer: Area of the shaded region is 6.867 square cm

Step-by-step explanation:

The shaded area corresponds to the difference of the area of the rectangle and the area of the semicircle.

Area of the rectangle = 4 times 8 = 32 cm^2

Area of the semicircle = 0.5 * pi * r^2 (where r is the radius, i.e., half of the diameters, i.e., 4 cm). So Area = 0.5*pi*4^2 = 25.133 cm^2

The difference: 32 - 25.133 = 6.867 cm^2 (area of the shaded region)

Logan and his friend went out to dinner and spent $18.50.They left a tip of $2.59.

maria [59]

To find this out, use a percent proportion, use cross products, and solve the equation.

$\frac{2.59}{18.50}= \frac{p}{100} \\ 18.50p=259 \\ \frac{18.50p}{18.50}= \frac{259}{18.50} \\ p=14$

So, the percent tip is 14%.
