Answers:
9). 45/9 = 5
10). 2 *14² = 2* 196 = 392
11). 5 * 12 * 7 = 60 * 7 = 420
12). 1/2 * 9 * 12 = 54
13).1/2(24)(9 + 21) = 12 * 30 = 360
14). 14 * 13 = 182
15). 16 * 8 * 5 = 640
16). 75/5 = 15
17). 2(5²) = 2 * 25 = 50
18). 8(2.5 + 4.2) = 8 * 6.7 = 53.6
19). 1/2(3)(5 + 6) = 33/2 = 16.5
20). 3.14(6²) = 3.14 * 36 = 113.04

Answer: 
Step-by-step explanation:
From the given picture, the radius of the base of the cylinder = 5.5 ft.
The height of the cylinder = 5 ft.+6 ft.=11 ft.
We know that the surface area of a cylinder is given by :-

Hence, the surface area of the given cylinder = 
Answer:
f(3) = 7
Step-by-step explanation:
Substitute x = 3 into f(x) , that is
f(3) = 4(3) - 5 = 12 - 5 = 7
