Answer: 55.7

Step-by-step explanation:

.5 + .5 = 1

1 + 13 = 14

6 + 4 = 10

10 + 10 = 20

20 + 30 = 50

50 + 5.7 = 55.7

charle [14.2K]

Answer:

A = 121 pi in^2

Step-by-step explanation:

The circumference is given by

C = 2 * pi*r

22 pi = 2 * pi *r

Divide each side by 2 pi

22 pi / (2 pi) = 2 pi r / (2pi)

11 = r

Now find the area

A = pi r^2

A = pi (11)^2

A = 121 pi in^2
