Answer:

105.12

Step-by-step explanation:

area of rectangle = 10 x 8 = 80

area of semi circle = 3.14 x 4^2     (4 because the diameter is 8 so half of it)

= 50.24

50.24 / 2 = 25.12 (as it is a semi-circle)

80 + 25.12 = 105.12

Answer:

130.24

Step-by-step explanation:

8*10+3.14*4^2=

80+50.24=130.24 ft^2

Cut the shape into a semi-circle and rectangle (with length 10 and width 8).

You'll find the radius of the semi-circle is 4.

The area of the rectangle is 80.

Then use the pir^2 formula but replace pi with 3.14

3.14 multiplied by radius 4 squared is 50.24

50.24 plus 80 is 130.24 ft squared.

AysviL [449]

Answer:

Step-by-step explanation:

The first choice is correct

The rate is 20 per dog, thus we get the equation:

c= 20d

However the first dog is free, so the equation becomes

c = 20(d - 1)

And he also has a walking fee of 85 dollars and thus the equation becomes

c= 85 + 20(d-1)
