The figure shaded was created by placing the vertices of a square within the circle. What is the area of the shaded region? Use 3.14 to approximate, remember to answer using cm2

30.985 cm squared

Step-by-step explanation:

first find area of circle

diameter is 11 so radius is 5.5

A = pi r squared

5.5 x 5.5 x 3.14 = 94.985

find area of square

A = base x height

8 x 8 = 64

subtract to get shaded area

94.985-64 = 30.985

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
