2) (G3-4 pts) Find the area of the shaded figure in square feet. Round to the nearest tenth if necessary. Circle the correct answer.
|--5---
18 ft
---5ft
A. 478.5 ft?
B. 311.2 ft
8 ft
C. 351.2 ft?
D. 438.5 ft?

Area of both triangles = 8*5 = 40

Rectangle Area = 8*18 = 144

Semi Circle Area = Pi*r^2 / 2 = (3.14159*81)/2 = 127.34

40 + 144 + 127.34 = 311.34 square feet

answer is B

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
