Answer:

67.5 ft^2

Step-by-step explanation:

First find the area of the circle.

A = pi r^2

A = pi (8)^2

A = 64pi

There are 360 degrees in a circle

The shaded area has 121 degrees

The fraction is 121/360

The fraction shaded is 121/360

The fraction of the circle is the same as the area

121/360 A = 121/360 * 64 pi

area shaded = 67.54488889

To the nearest tenth

area shaded = 67.5

Can i get some help :

Answer:

b = $\frac{7}{12}$

Step-by-step explanation:

b + $\frac{2}{3}$ = 1 $\frac{1}{4}$ ← change to an improper fraction

b + $\frac{2}{3}$ = $\frac{5}{4}$

Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions

12b + 8 = 15 ( subtract 8 from both sides )

12b = 7 ( divide both sides by 12 )

b = $\frac{7}{12}$
